MULTIFUNCTION REFERENCE CLASS METER

650 Multifunction Reference Class Meter Data Logger. Temperature, Pressure, Vacuum, CO, CO2, rpm, mV and mA and % RH.
Accurate temperature measurements are becoming increasingly important, especially in 
regarding energy savings, indoor air quality and environmental protection.
Limitless future options available with the NEW modular system.
Special advantage: automatic correction of absolute pressure for accurate measurements. aw value measurement with trend display and automatic recognition of equilibrium.

Multifunction Meter Datalogger

  • 3 user defined function buttons

  • Saves or prints at the touch of a button

  • Mains connection/fast recharging

  • Attachable printer

  • Data communication by PC

  • Barcode pen

  • 2 user defined probe sockets, automatic
    recognition of all connected probes

Our 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 latest technology. Accurate temperature measurements of liquids, semi solids, air and surfaces are performed by RTD (Pt 100) probes according to DIN IEC 751. 
The instrument can be used for all measurements requiring a high accuracy e.g. measurements in chemical labs.

Description

The precision temperature/humidity measuring instrument includes the basic parameters
temperature, CO, CO2, rpm, mV and mA 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:
    - relative humidity (% RH)
    - dew point, pressure dew point (tp, tdp)
    - absolute humidity (g/m3)
    - humidity levels (g/kg pressure-compensated)
    - humidity, wet temperature °C and °F
    - water vapor partial pressure in mbar/hPa
    - Enthalpy kcal/kg

    Humidity probes for every application, from low to high humidity levels

    Guaranteed long-term stability < 1% over 2 years

    Highest accuracy up to ± 1 %
