High Accuracy PT100 RTD Input Thermometers

HIGH ACCURACY PT100 RTD INPUT THERMOMETERS

The Omega HH804U is a high accuracy RTD input thermometer. These handhelds work with 100 . platinum PT100 RTDs and are selectable for 3 different temperature coefficient curves. These units comply with ITS-90. Both come standard with a built in USB port and DC power jack. Optional Windows software and AC adapter allow real time data logging to PC for extended periods. The HH804W model features a quick and easy to use wireless interface instead of USB. This allows real time data transmission at distances of up to 75′.

TOP FEATURES:

Programmable Alarms: Audible Hi/Lo limit alarms that alert the user when thresholds are exceeded.
Data Management: Functions include MAX/MIN, AVG (average), REL (relative), and HOLD.
Curve Selection: User-selectable for three different temperature coefficient curves (Pt385, Pt3926, and Pt3916).
Durability: Includes a protective rubber boot and is powered by 4 “AAA” batteries with approximately 200 hours of life.
