Product Highlights

The TMD90A is a dual input thermometer that offers a wide temperature range and accepts type K, J, T, R, S, and E thermocouples and is ideal for HVAC/R technicians, electricians, research, industrial process, and quality control. The dual inputs allow easy super-heat and sub-cool temperature measurement as well as cut-out and in temperature measurements. The triple display with backlight shows T1, T2, and T1 – T2 and includes hold, min/max, relative, and timer/date stamp functions. The TMD90A supports dual channel real time data acquisition using the built-in RS-232 interface and optional software and data transfer cable (Model TM-SWA).

    Good product

    I have had this product for years and it does exactly what it needs to do without too many unecessary options. The only thing I would like better is if it had some sort of rubberized case to make it a bit more durable.

    ✔ Yes, I recommend this product.

    Good meter

    I,ve used this meter in the “Metermann TMD90” version for several years.
    Nice meter, also does hold it’s specs over time very well.
    The housing is a bit hard plastic type, but acceptable.
    It holds well.
    Lots of sensors available that all fit this meter.
    The dual screen is very handy.
    For long measurements, it is recommendable to purchase an additional mains adaptor.
    Good value for money

    ✔ Yes, I recommend this product.
