1. Constant temperature control 2. Timing switch constant temperature control 3. Cycle timing switch constant temperature control 4. Digital electronic temperature controller ,It is an accurate temperature controller,The temperature can be quantized by digital quantization,Using sensor,The color of the fuselage adopts Pearl White and mirror reflective resistance. Product specification: Input voltage range:100~240V AC Maximum output current:10A Rated working frequency:50/60Hz Range of temperature measurement:1-99 Precision of temperature measurement: +/- 1 Temperature resolution:1 Line: 2meter Use of attention: 1.This product is not waterproof,So 't put this product into water when measuring the temperature of water,The probe is waterproof,So the water temperature can be measured by putting the probe in the water. 2.The input voltage can not exceed 250VAC. 3.For , it's better to connect the Ground wire. failure Causes and : 1.Input voltage no response ,Check if there is a AC220V voltage input,Check the plug. 2.display "Er",Check whether the probe is connected and in good contact. 3.After setting the temperature,The arrival temperature relay is not absorbed,Check whether the pattern is correct,Whether the timing constant temperature function is opened. Plug Type:US Plug,it applies to Canada, India, Mexico, Thailand, the , the Philippines,Taiwan and so on. colour: white Material: plastic Size: 145x37x60mm Package Contents: 1 x temperature controller 1 x probe 1 cord Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
