Frequently Asked Questions

What is the accuracy of your digital temperature humidity controllers?

Our controllers offer high accuracy: temperature measurement has an accuracy of ±0.5% of full scale or ±0.5°C, whichever is greater, and humidity accuracy is ±3% RH (relative humidity) under standard conditions. For example, in a typical range of 0-100% RH, you can expect no more than ±3% RH deviation. This accuracy is maintained over a wide operating temperature range (-10 to 55°C for the controller), ensuring reliable readings in various industrial environments. To achieve maximum accuracy, we recommend using high-quality sensors and performing periodic calibration. Our controllers also feature automatic compensation for sensor drift, further enhancing long-term precision. If you require even tighter control, we can provide models with enhanced accuracy options.
Absolutely! As a manufacturer with extensive OEM/ODM experience, we offer comprehensive customization services. You can customize the casing design, display screen, keypad layout, firmware features, and control algorithms to match your unique requirements. We can also adapt input/output configurations, adding extra relays, analog outputs, or communication protocols as needed. Our engineering team will work closely with you to understand your application and develop a tailored solution that meets your performance and branding needs. We have partnered with numerous global brands to deliver custom controllers that enhance their product lines. Whether you need a small batch for prototyping or large-scale production, we ensure high-quality and cost-effective customization.
Selecting the appropriate sensor depends on your operating environment, temperature range, and desired accuracy. For temperature, common options include thermocouples (types K, E, J) for high temperatures (up to 1200°C) and RTDs (PT100) for better accuracy and stability in lower ranges (-200 to 850°C). For humidity, capacitive sensors are standard, offering accuracy of ±2-3% RH and good long-term stability. Consider factors like exposure to chemicals, moisture, and vibration. For harsh environments, use sensors with IP67 or higher protection. Your controller should be compatible with the sensor output: thermocouples provide millivolt signals, RTDs can be 2, 3, or 4-wire, and humidity sensors often provide 4-20mA or 0-10V outputs. Our technical team can assist in sensor selection and provide wiring diagrams. We also offer sensor kits with pre-calibrated units for plug-and-play integration.
Yes, many of our controllers are equipped with RS485 communication using Modbus RTU protocol, which is widely adopted in industrial automation. This allows you to connect multiple controllers in a daisy-chain network, with each controller having a unique address. SCADA or other master systems can read real-time values (temperature, humidity, setpoints, status) and write control commands (setpoints, auto/manual mode) to each controller. This enables centralized monitoring and control of distributed environments. For Ethernet-based systems, we offer models with built-in Ethernet or Wi-Fi connectivity, or you can use a Modbus-to-Ethernet gateway. Our communication interface is well-documented, and our support team can provide configuration guidance. Integration is straightforward, saving you time and enhancing system intelligence.
We provide a standard 2-year warranty for all our digital temperature humidity controllers, covering defects in materials and workmanship. During the warranty period, if a product fails under normal use, we will repair or replace it free of charge. Beyond warranty, we offer cost-effective repair services and carry a large inventory of spare parts. Our after-sales team is available 24/7 to provide technical support, troubleshooting guides, and remote assistance. We also provide downloadable manuals, software updates if applicable, and application notes. Additionally, our sales engineers can offer installation and commissioning support for complex projects. We believe in building long-term relationships, and our customer service reflects that commitment. Your satisfaction is our success.
