    With the subject of Indoor Air Quality becoming more prominent and recognised throughout many different industries, it has become essential to be able to accurately monitor low levels of indoor pollutant gases.

    The htV-M can precisely measure formaldehyde concentrations in parts per million (ppm) and mg/m3 over a wide range of temperature and humidity. Fast and easy to use, pressing a single button gives an immediate indication of concentration levels.

    The improved Formaldemeter htV-M is reliable and simple to calibrate. The compact size means the htV-M is small enough to be used as a hand held device. The built in memory and real time clock enables the htV-m to log all 3 parameters and corresponding times, allowing improved monitoring and analysis opportunities.

    Alternatively a PC can automate the sampling and log data at specific times by a direct or wireless connection. This is advantageous as it allows the user more freedom and is a cost effective approach to taking such measurements.

    Formaldehyde Sensor

    Type: Electrochemical manufactured by PPM Technology..
    Range: 0-10ppm as standard (0- 12.3 mg/m³ at 25°C).
    Extended range available on request.
    Resolution: 0.001 ppm
    Precision: 2%
    Accuracy:


     
    94% of all instrument readings meet the NIOSH criteria for an acceptable method when measuring 0.3ppm of formaldehyde over a relative humidity range of 25-70%. The NIOSH criterion for acceptability is that all results fall within ±25% of the true value at the 95% confidence level.
    Calibration: By user with supplied calibration standard or by original manufacturer.

     

    Temperature & Humidity Module

    Type: Interchangeable digital CMOSens®..
    Range: -40 to +128°C, 0–100% RH
    Accuracy: ±0.4°C, ±3% RH
    Optional upgrade to ±0.3°C, ±1.8% RH

    Kit Contents:

     

     

    • Formaldemeter htV-M instrument with stand
    • Formaldehyde calibration standard tube
    • USB cable
    • Pack of phenol filters (10)
    • Thermometer
    • Ballpoint pen
    • Download Software (data download and device settings)
    • Operation manual on CD
    • Mains Adapter


    Optional accessories:

    • Calibration Standard: PPM supplies an easy-to-use formaldehyde calibration standard tube for checking and adjusting the calibration of the Formaldemeter htV. The tube produces a known concentration of formaldehyde vapour that can be sampled by the instrument to check accuracy and performance. The standard has a 100-sample capacity or a useful life of six months (whichever occurs sooner).
    • Desk Stand
    • Wall bracket
    • Pack of phenol filters (100pcs)
    • SPC-3 software (viewing and recording of real-time readings on the PC, alarm thresholds, generating curves and reports)
