Applications
Coffee roasting equipment
Manages rapid temperature changes during roasting to achieve consistent roast levels. Real-time adjustments prevent burning or under-roasting, preserving aroma and flavor.
Beer brewing equipment
Controls fermentation temperatures to optimize yeast activity and flavor profiles. Monitors and adjusts heat during mashing, boiling, and conditioning stages to prevent off-flavors.
Printing equipment
Stabilizes temperature in processes like ink drying or toner fusing. Prevents overheating or underheating that could cause smudging or misalignment, enhancing print quality.
Injection molding equipment
Ensures precise temperature regulation of plastic resin in barrels, nozzles, and hot runners, reducing defects like warping or incomplete fills and improving part quality.
Plastic bottle manufacturing
Regulates heat in extrusion and blow molding processes to maintain resin viscosity and mold integrity. Prevents defects such as uneven wall thickness.
Oven and furnace temperature control
Maintains uniform distribution heat in industrial ovens, kilns, or furnaces, dynamically adjusting heating elements to compensate for load changes or heat loss.

Frequently Asked Questions
What Does The CH102, CH402, CH502, CH702 and CH902 Mean?
CH series PID temperature controller is our company’s most popular product in the market. Different models correspond to different panel sizes, which are CH102: 48*48 mm, CH402: 48*96 mm, CH502: 96*48 mm, CH702: 72*72 mm, and CH902: 96*96 mm respectively.
Application of CH Temperature Controller
These PID temperature controllers are mainly used to control the temperature of heating element, it is widely used in food machines, plastic production equipment, hospital high temperature disinfection, laboratory and so on.
What Is The Output Of CH Series Pid Temperature Controller?
Our CH series PID temperature controller default output can be SSR+relay, 4-20 mA or 1-5 VDC, if the output is SSR, you can use it with our DC/AC solid state, if the output is relay, you can use it with our AC/AC solid state relay or AC contactor.
How Do These Temperature Controllers Work?
These PID temperature controllers work based on the PID algorithm, which can keep the temperature at a stable temperature without fluctuations. It is a mature control technology.
What Are The Prices Of them?
These temperature controllers of ours are of high quality, generally our CH series temperature controller price is less than US$10.0.
Can Your Company Provide ODM Or OEM Service For Me?

Please download it by this link: Lorentzzi CH series PID Temperature Controller User Manual
What Are The Differences Between Our REX And CH Series PID Temperature Controllers?
The functions and control technology of these two series of PID temperature controllers are the same, the difference is the appearance and length. The CH series is more attractive than our REX series PID temperature controller and is shorter in length(CH series housing length 78 mm, REX: 110 mm).
What Are The Differences Between Your CH Series And TCN4 Series Temperature Controllers?
Our CH series PID temperature controllers are low cost and enomonical products, which are very popular and well-known in the market.
While our TCN4 PID temperature controller is our newly developed product, which has a clear and bigger digital display, and the inner program is very user-friendly, also it has a fast 100 ms sampling time, which can realize more accurate temperature control.
