Handheld dewpoint hygrometer is intrinsically safe
The unit is certified intrinsically safe to II 1G/EEx ia IIC T4 for use in hazardous areas and automatic calibration and dry-down technology achieve very rapid, reliable and accurate readings
The robust, ergonomically designed housing incorporates the moisture sensor, signal conditioning circuitry, memory management, 128x64 dot graphics display, five key membrane keyboard plus on-board rechargeable lithium ion battery.
This self-contained digital unit is user-friendly and eliminates the problems experienced by operators and technicians with the bulky size, weight and even analogue readouts associated with the previous generation of traditional dewpoint meters.
The ultra high capacitance aluminium oxide sensor is housed in a desiccant dry-down chamber to ensure immediate readiness for operation.
Selectable moisture and pressure units are available to cover a -110 to +20C dewpoint (or equivalent) measuring range, at atmospheric pressure, with pressure compensated dewpoint values automatically calculated where required.
User selectable units for display include C, degF, ppm(v), ppm(w), ppb, g/m3 and lb/MMSCF.
Graphical representation of all logged data can also be selected for display.
Meters can be battery or mains powered, with over 250 hours continuous operation from a single recharge.
Auto shut-down, with battery life icon is also incorporated for maximum effective battery life.
All units are supplied as standard with battery charger, connection fittings, a 2 metre length of PTFE sample pipe, together with instruction manual and calibration certification traceable to NPL.
Optional features include: carrying case, 4-20mA loop powered output and RS485 serial communication.
Development work is also in hand for the production of an intrinsically safe model for use in hazardous conditions.
