The Edgetech Instruments Model ELH Series is a series of precision humidity chambers, with NIST traceable accuracies in humidity (±0.5% typical), temperature (±0.1°C) and dewpoint (±0.2°C). The ELH Series consists of a programmable controller for constant precision control and uniformity, and an integrated DewMaster chilled mirror hygrometer for accurate temperature and humidity measurements.
The ELH series offers three standard chamber sizes: 1.5cu.ft., 6cu.ft. and 10cu.ft. Larger volume chambers are also available. All chambers use an environmentally safe non-depleting refrigerant.
The Model 1500 is a drift-free, low maintenance hygrometer featuring high durability, NIST traceable certification, and ease of use. Its primary method chilled mirror sensor provides precision dew/frost point temperature measurement in a robust, transportable package.
Simply attach the sample line, adjust the flow with the integral flow meter and turn on the power. Within minutes you will be collecting field dew/frost point data with the same chilled mirror accuracy of a laboratory standard hygrometer. With a nominal battery life of 12 hours, you will be able to collect data for the entire shift or spot-check your processes for several days without recharging.
The Edgetech Instruments Model DewTrak II dewpoint/humidity transmitter is an optical chill mirror hygrometer designed to continuously measure the moisture content in gases. The instrument is powered by 24Vdc.
The DewTrak II uses the chilled mirror dewpoint temperature condensation principle to determine the water vapor concentration in gas mixtures, and a platinum resistance thermometer to accurately measure that temperature. Outputs include 4 to 20mA, 0 to 5 Vdc, or 0-10Vdc and an RS232 serial port as well as electrically isolated relay contacts.
The Model OxyTrans is an easy to use, accurate and economical way to measure Oxygen at trace and % levels.
A simple display and one-point calibration allow for a quick start of the instrument.
Edgetech Instruments’ services are performed in the USA at their modern, well-staffed, ISO/IEC 17025:2005
accredited, ISO 9001:2015 registered manufacturing facility. All recertifications and calibrations are traceable to
NIST.
