A lot of people asked about the quality of the product, I now put the product movement photos posted, let us know about our quality, but also to eliminate everyone's doubts
1, you can see that we have two products in the same CPU, which is a reliable guarantee of reliable operation. More than 90% of the temperature controller on the market is single chip
2, our relay is Taiwan GOODSKY or OEG, which is in the relay industry well-known brands in the industry, other companies with domestic brands more Songle and Acer, friends can understand the electronic apart compare. This device is a device is the key, because the control of the whole of the thermostat results it is through this device in response to it, the quality of which directly determines your thermostat for how long, but now most people are in it to cut corners, because this is not a thing almost can not be used to buy back, like to use a time to reflect, but then you have confirm receipt, but also gave praise, there are Everfount people continue to be fooled. We inside is a 10A relay, but we tell you the biggest 5A application, because the relay is not full load. For that, life will be shortened, if installed inside the 5A relay, tell the user can use the 5A maximum, it is extremely irresponsible. Resistance load is the maximum current of 70% 50%. maximum current, inductive load
3, our transformer (that is the red one) is potting, the advantages of potting transformers is not afraid of vibration, heat is also very low
4, most parts of the machine adopts SMT machine chip, the process is excellent, this is the quality assurance, higher than manual welding reliability
5, many friends may ask why there are still empty components, that is reserved for WH7016E or WH7016H and other functions of more models, this compatible design can effectively reduce the enterprise inventory pressure and cost control, equivalent to the platform design of the car
What is good, we used to know, we are very focused on product durability and practicability, a lot of things will not sell go bad, it is very rare, unless the quality is very bad, but for a period of time bad very common, so we welcome old users in the use of later comments,
How to choose the thermostat correctly:
1: select the right temperature control range: we have -50-110 degrees, -9.9-99.9 degrees, -30-300 degrees range optional
2: selection is one-way control, or two-way control, only control heating or refrigeration, a load is called one-way control, to control the heating and cooling load is called two-way control,
3: select the control power, some of our models have 10A and 30A two kinds of relay optional, 10A relay can receive maximum load 1000W, 30A relay can receive maximum load 2000W, more than the maximum temperature control power, please contact the external contactor
4: selects the control resolution (i.e., step by step), to 1 degrees, or 0.1 degrees
5: select the correct power supply voltage
6: select the type of probe needed
The metal probe is suitable for measuring air and there is no corrosive liquid. The characteristic is quick reaction.
Plastic probes are suitable for measuring corrosive liquids such as sea water, with slow reaction and corrosion resistance.
Threaded probe is suitable for mass production equipment installation.
4 point probe is a special probe for water pipe.
Our thermometer supports probe lines extending to a maximum length of 100 meters. Ordinary line can be. Need to pay attention to: probe line and power line not long distance parallel line, need long distance parallel line as far as possible to use double core shielding line, inside two line probe, outer shield network grounding.
Brief description of each model:
One way control:
WH7016C:-50-110 degree one-way control, control resolution of 1 degrees, without overheating alarm output
WH7016D:-30-300 degree one-way control, control resolution of 1 degrees, without overheating alarm output
WH7016E:-9.9-99.9 degree one-way control, control resolution of 0.1 degrees, with overtemperature alarm output
WH7016G:-50-110 degree one-way control, control resolution of 1 degrees, with overtemperature alarm output
WH7016J:-30-300 degree one-way control, control resolution of 1 degrees, with overtemperature alarm output
WH7016H:-50-110 degree bidirectional control, control resolution of 1 degrees, with overtemperature alarm output
WH7016S:-9.9-99.9 degree bidirectional control, control resolution of 0.1 degrees, with overtemperature alarm output
WH7016K:-50-110 degree bidirectional control, control resolution of 1 degrees, with overtemperature alarm output, semiconductor refrigeration chip dedicated
WH7016R:-9.9-99.9 degree bidirectional control, control resolution of 0.1 degrees, with overtemperature alarm output, semiconductor refrigeration chip dedicated
