17 TEMPERATURE/HUMIDITY RECORDER One model has it all! The THDx offers you an affordable means of documenting temperature, humidity, and dew point. Its accuracy and flexibility make it the instrument of choice for quality control, compliance to regulations, or human comfort. The semi-conductor temperature sensor offers ±1.8 F (±1.0 C) accuracy; the thinfilm humidity sensor offers ±2% RH accuracy between 10 and 90% RH. A large LCD simultaneously displays temperature and humidity or temperature and dewpoint. All the recording parameters (temperature range and scale, humidity or dewpoint scale, and rotation time) are set by you, using a keypad and dip switches, and you can change them as often as your needs dictate. Use the front panel keypad to also select alarm parameters; the audible and visual alarms let you know when high or low limits are exceeded. The sensing probe is on 15-feet of cable and is ideal for remote monitoring and documentation in harsh or clean environments.

Search and Measure moisture meter modes distinguish subsurface moisture from surface moisture in materials and the Condensator mode confirms the presence - or otherwise of condensation on surfaces. M2384E The Search Mode allows the user to establish if there are high moisture levels within material that warrant more detailed investigation. In the Measure Mode actual moisture content values for wood and wood moisture equivalent (% WME) values for masonry are displayed together with text messages that tell the user if the material is in a dry, borderline or damp condition. In the Hygrometer Mode this meter can be used to measure relative humidity, ambient temperature and dew point.

25 MOISTURE METER A dual function instrument that combines the proven two-pin inspection method with a new non-invasive radio frequency technique. The result is a new moisture meter for rapid and thorough inspection of buildings for dampness on and below a surface. This easy-to-use instrument employs two electronic circuits: The first is for the conventional two-pin method which shows whether a surface is dry, damp or wet. This is known as the Measure Mode. For the Measure Mode the meter has a socket for a two-pin headand-lead (for awkward corners) and a set of Deep Wall Probes (insulated but for their tips) for the measurement of moisture conditions of a wall regardless of surface dampness and surface contamination by salts. The second is based on radio frequency emissions with the electronics located in a bulge at the back of the instrument. It is capable of measuring moisture through many wall and floor coverings and ceramic tiles. This is known as the Search Mode. For the Search Mode, in order to accommodate the sophisticated RFE electronics, there is a bulge at the back of the meter. For an instant display of degrees of dampness below a surface, this is simply held against, and in contact with, the wall. In the Search Mode the meter has a user adjustable AUDIBLE ALARM emitting a variable tone depending on the level of moisture. The incorporation of an audible tone means you can identify areas of concern even when you cannot see the LED scale e.g. at height and around corners. RANGE MEASURE Mode: 6% to well above fibre saturation in wood and beyond (to nominal 100) SEARCH Mode: Relative, colour-coded CALIBRATION MEASURE Mode: Wood moisture equivalent SEARCH Mode: Relative RESOLUTION MEASURE Mode: ± 0.1% SEARCH Mode: Not applicable DISPLAY MEASURE Mode: Three digit LCD and synchronized green, yellow & red LED display SEARCH Mode: Green, yellow & red LEDs AUDIBLE ALARM SEARCH Mode only: Adjustable synchronized with LED display GENERAL Operating Temp.: -10 to +45 C Two LR6 batteries 165 x 52 x 40mm 200 g BLD5360 Dual Function Moisture Meter $ MOISTURE METER Two versatile measuring modes, measures moisture content plus relative humidity, temperature and dew point with plug-in RH probe User can switch between moisture meter and hygrometer probe Moisture Mode operates on an electrical impedance measurement principle Non-destructive moisture measurement Hygrometer Mode uses a solid state capacitive sensor RH probe Instant readings on clear dot matrix LCD display Choice of scales to suit different types of floor slabs and screeds Stores up to 900 recorded readings in 30 files Recorded readings can be recalled and displayed Download recorded readings to a PC MOISTURE MODE Concrete: 0 to 7%; Anhydrite & Gypsum Screeds: 0 to 12 (comparative); Reference 0 to % MC concrete Resolution: HYGROMETER/RH MODE 5 to 98% RH; 14 to 120 F (-10 to 50 C) Resolution: 0.1% RH; 0.1 C GENERAL 9V PP3 Li-Mg battery Display: Dot matrix LCD Meter: 150 x 80 x 35mm (6 x 3 x 1.4 ); Probe: 110mm L x 10mm dia.

26 MOISTURE DETECTOR For non-destructive moisture evaluation of EIF systems For tracing moisture back to source Fast and easy to operate Instant clear readings Lightweight, handheld, battery-operated The location of excess moisture and decay behind an exterior insulation finish (EIF) wall cladding system can be difficult and near impossible, as normally, evidence of this moisture and decay are not visible on either side of the wall. Excess moisture can be hidden and trapped in the substrate and within the thickness of the wall. If these conditions are allowed to continue, the moisture will increase, as will the rot and decay, eventually leading to possible failure of the cladding system and the structure. Also wet insulation loses its thermal value resulting in unnecessary heat loss or gain and thermal movement in the structure. So in the interest of all concerned, early detection of these problems or potential problems and corrective remedial action makes good economic sense. The Wet Wall Detector has been specifically developed for the detection, location and tracking of excess moisture within and behind EIF systems. This electronic instrument will read through fibre reinforced lamina and exterior insulation to locate and evaluate excess moisture that may be present in the sheathing substrate and wood stud. The Wet Wall Detector works on the principle of electronic impedance. With impedance measurement, harmless signals are transmitted from the electrodes at the base of the instrument deep into the thickness of the wall. These signals measure the change in electronic impedance which is translated into a relative moisture content reading and instantly displayed on the large analog dial. Readings are instant and continuous. The Wet Wall Detector is also fitted with and audible device which sounds at high readings. The Wet Wall Detector is non-destructive in operation which means that it can detect excess moisture without the need to mechanically probe, cut or damage the surface. The Wet Wall Detector will give vital information necessary to evaluate and carry out moisture assessment on the condition of most fibre reinforced EIF systems of wall cladding and similar systems at an affordable cost without complications. TRX2004 Wet Wall Moisture Detector $ MOISTURE DETECTOR No need to drill or mechanically damage the surface Instant readings with reproducible results Easy-to-read, analogue dial Pocket-sized, measures 6" x 3" x 1.3" and weighs only 10.5 oz. Battery-operated Robust, extruded aluminum housing Regular checking of moisture content during the drying out period of a new concrete floor or floor screed is important to ensure it has reached sufficient dryness to accept the floor covering. Excess moisture in the concrete could cause latent problems such as condensation or failure of the adhesive under the floor covering. The Concrete Encounter will give you an instant reading of moisture content up to 6% concrete, up to 9% gypsum screed, enabling you to make an informed decision on when to install the floor covering. To use, simply switch on and hold the instrument firmly against the surface. The electrodes must be in direct contact with the concrete surface, which must be smooth and free from dust. As many non-destructive tests as you need can be can then be carried out in seconds without the need to drill or damage the concrete. 262 M724E CME4 Concrete Moisture Detector $740.00
