Item Type: Digital Thermostat Model: MH-2000 Material: ABS Voltage: AC 90V~250V Uses: water quality testing, aquaculture, industrial temperature control Working Voltage Range: AC90V~250V10%50/60Hz Whole Machine Power Consumption: 3W Standby Power Consumption: 0.5W Temperature Control Range: -40~120 Measurement Error: 0.3 Temperature Control Accuracy: 0.1 Resolution: 0.1 Temperature Difference: adjustable between 0.1~30 Temperature Probe: NTC25=10K B3435 1% (cable length is 1.4m/4.6ft) Relay: 10A/AC220V Working Environment Temperature: -20~70; humidity, 90%RH without condensation Package List 1 x Digital Thermostat 1 x Manual 1. In order to prevent highfrequency interference, the sensor line cannot be bundled with the power line and load equipment during installation, and must be separated and independently wired.2. The power supply and the marked voltage of the host must be consistent, and the deviation of the rated voltage value shall not exceed 10%. Strictly distinguish the sensor, power cord and load output interface during installation.3. The thermostat host cannot be installed where there is dripping water or where the elderly and children can touch it. 1Using modern heating technology, the smart thermostat is small in size, light in weight, easy to carry, and does not take up space. 2Simple to operate, its temperature measurement and temperature control is accurate with strong antiinterference ability. 3It is a fully intelligent control system suitable for most users to use in various heating/cooling equipment in different environments. 4With the permanent memory function of the set parameters, it is suitable for water quality testing, aquaculture, and industrial temperature control. 5All parts have been carefully selected, the working performance is more stable, the measurement error is small, and the accuracy is high.
