    Tips: How to maintain the portable digital dew point meter?

    1. Cleaning and storage

    • Avoid cleaning the dew point meter with corrosive or solvent-based substances to prevent case damage.
    • Wipe with a clean wet cloth and detergent and store in an appropriate area of temperature and humidity.
    2. Replace battery
    • When the battery is low, replace the 9V battery and securely close the battery compartment. Do not dispose of used or rechargeable batteries with household waste.
    • Users are legally required to return used batteries to designated collection points, retail stores, or other authorized battery distributors. Do not discard the portable dew point meter with household waste. End-of-life equipment must be taken to an authorized electronic waste collection facility for proper disposal.

    3. Replace the probe

    • Turn the connecting nut clockwise and disassemble the old probe.
    • Replace the new probe: Connect the connector, slowly rotate the connector to find the docking hole position. After the hole position is aligned, tighten the connecting nut counterclockwise. After 2-3 turns, gently push the probe towards the long rod until the connecting nut is tightened. Then continue to tighten the nut until it is tightened. If you have any questions about replacing the probe, please contact the ATO online store.

    Dew point meter extension cable
    Do you have an extension cable for your handheld dew point meter? I plan to buy a new one. It will be used as a calibration reference standard in my climate chamber.

    ATO Responded
    Sorry, this unit SKU: ATO-DPM-HG970 does not currently have an extension cable. However, we have another model that supports a 600mm high-temperature probe or a high-temperature probe with an extension cable. Are you looking for a portable dew point meter with an extension cable and a 600mm probe?
    Dependable handheld tool
    I’ve been using this portable dew point meter for routine environmental checks, and it has been extremely reliable. It measures dew point, temperature, and humidity accurately, and the wide -30~80°C range makes it suitable for both lab work and on-site industrial inspections. The device is easy to operate, responds quickly, and has helped a lot in verifying and controlling environmental conditions during engineering tasks.
