Handheld Hygrometer Model 650

Accurate Humidity measurements are becoming increasingly important, especially in regarding energy savings, indoor air quality and environmental protection.

This new modular system approach allows you to purchase the instrument that currently meets your measuring requirements, yet is capable of being upgraded at a later time for your future measuring needs.

These meters are supported with our user-friendly, Basic Comfort software, which can be used for programming, data processing, and even bar-coding. The optional barcode pen allows for very quick and easy data processing. Our modular design allows for easy upgrades to the instrument as they are developed. In this way you will always have a measuring instrument corresponding to the lastest technology.

1% Precision Humidity probe - Unmatched Accuracy!

The Model 650 incorporates a 1% maintenance free humidity probe ideal for checking humidity measurements for validation of critical environments. It's rugged, compact and protected by a water proof plastic housing. The Humidity measuring range is 0-100%RH with an accuracy of ±1% 10-90%. The accuracy of this probe has been tested and proven time and again in worldwide laboratory tests. The probe is equipped with a patented %RH sensor.

Benefits:
• Guaranteed two year long stability
• Humidity sensor is unaffected by water
• Highest % RH measurement accuracy with a capacitance probe
• NIST Certification verses a N.I.S.T. traceable standard
• Proven accuracy by worldwide laboratory tests
• Battery powered
• Unit has data logging capabilities and/or small attachable printer

Description:
The precision temperature/humidity measuring instrument includes the basic parameters - temperature, dew point and %RH.
• Rapid Measurement with accurate temperature probes. The measuring instrument extrapolates the final value.
• Highest precision due to system calibration (measuring instrument + probe). Calibration data is saved in the probe.
• Calculates all of the physical humidity parameters in the Mollier diagram:

• Humidity probes for every application, from low to high humidity levels
• Guaranteed long-term stability < 1% over 2 years
• Highest accuracy up to ±1% (10-90%; ± 2% remaining range)
