HYGROMASTER
Cost effective Portable RH, Temperature and
Dew Point Indicator

Advanced portable, battery operated measurement for
checking a wide variety of environmentally controlled spaces.

The Hygromaster is a convenient, durable, hand held thermo-hygrometer for use across many industries and applications.
It may be used to measure relative humidity (RH), temperature and dew point. Its large LCD displays RH, ambient and dewpoint temperatures for easy viewing. An optional surface temperature probe accommodates a range of additional uses. The Hygromaster has a uniquely designed removable Hygro-stick probe system that is independently calibrated from the instrument. The system allows the use of multiple probes with one meter. Simple replacement of the probe substantially reduces instrument service downtime. The meter is supplied with carrying pouch, Hygrostick and instructions.

Features:

	Displays - %RH - Air Temperature - Dewpoint - Surface Temperature
	Large LCD display in 0.1% increments
	User select - °C or °F
	User select - auto shut off between 0 and 9 minutes
	Reading hold
	2 x AA batteries (supplied)
	Pouch with belt loop
	Accuracy better than 2% RH

Benefits:

	Modular, replaceable Hygrostick probe
	Probe may be calibrated independent of meter
	Interchangeable probes eliminate downtime
	Robust design
	Factory calibrated
	3 point NIST traceability (optional)

Applications:

	HVAC Building Control
	Energy Management Systems
	Indoor Air Quality (IAQ)
	Clean Rooms
	Pharmaceutical
	Museums/Archives
	Building Restoration
