Superheat / Subcooling Computer. This highly accurate instrument measures Temperature, Temperature Differential, Humidity, Dry-bulb, Pressure, Superheat, Sub-cooling and more!  The memory is loaded with 15 different refrigerant charts and has the capacity to add new and different refrigerants at a later date. Displays Min, Max and Average values. As shown, the standard unit includes one each model 1075 & 4011 temperature probe. Choose the 500 or 1000 PSI rated pressure probe in order to directly read super-heat and sub-cooling. (Pressure may also be entered by user to calculate Superheat or Sub-cooling)  To measure super-heat, just attach the temperature probe to the system suction line near the compressor, then attach the pressure transducer to the system access port near the low side of the compressor. Sub-cooling is measured in the same way, except the temperature probe is attached to the liquid line, and the pressure probe is attached to the high side access port. The MFM300 will determine if the reading is super-heat or sub-cooling and will display the appropriate label. RH Probe and Pressure Probes may be added as needed - See the options below.

Solar Powered Digital Thermometer

These solar-powered Instruments represent the “next generation” in industrial thermometers. The bold, hi-contrast display is easily read from greater distances than the typical glass tube thermometer. The unique design includes bi-directional solar panels, allowing the unit to collect light from multiple planes and providing reliable service in even the most dimly lit installations.  The MJ-CDX9 Industrial Thermometer is furnished in one standard temperature range (-58 to 302°F & -50  to 150°C) which is switchable in the field. This wide range covers most applications for this type of product, while offering an environmentally friendly alternative to the commonly specified mercury-in-glass thermometer.
