Traceable unit displays humidity to 0.01%, use for QC, ISO 9000, AND R/D

Traceable Digital Hygrometer/Thermometer/Dew Point instrument, by using a special breed of artificial intelligence, with a resolution of 0.01% RH, 0.01°F/°C, and 0.01 dew point/frost point °F/°C. It samples once per second. Fuzzy logic algorithm pinpoints the exact answer almost instantly.

Fast response with high accuracy

Direct-reading instrument has an accuracy of ±1.5% RH, 0.01 RH resolution and reads from 10 to 95%RH. Results are reported in both °F and °C from –40.00 to 220.0°F (–40.00 to 104.0°C) temperature, and from –40.00 to 140.0°F (–40.00 to 60.00°C) dew point/frost point. Temperature resolution is 0.01° with an accuracy of ±0.4°C.

Certified Traceable to NIST

Multi-point calibration on an individually-numbered Traceable Certificate which assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.

Clean room and food applications

Four-digit LCD can be read from 10 feet. Rugged handheld unit is designed for years of service.

Hi/Lo memories, programmable alarms, and data output

When an out-of-range condition is sensed, an alarm sounds and the display flashes.
