Hygrometer is certified intrinsically safe
The new SADPminiEx hygrometer combines the proven reliability and excellence of ultra-high-capacitance aluminium oxide dewpoint sensor with state of the art electronics.
Comprehensive measurement of moisture levels
The application of modern microelectronics means that systems are now available that make it economically viable to monitor moisture concentration at all points of use where it is of importance
The robust, ergonomically designed housing incorporates the moisture sensor, signal conditioning circuitry, memory management, 128 x 64 dot graphics display, five-key membrane keyboard plus onboard 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 degrees Celsius or Fahrenheit, parts per million by volume or weight, parts per billion and grams per cubic metre.
Graphical representation of all logged data can also be selected for display.
Meters can be battery or mains powered, with over 250h continuous operation from a single recharge.
Auto shutdown, with battery life icon is also incorporated for maximum effective battery life.
All units are supplied as standard with battery charger, connection fittings, a 2m 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.
