The bimetallic thermometer is a temperature-measuring device that uses two different metal strips with varying rates of thermal expansion.
As China Bimetallic thermometer Manufacturers and Industrial Bimetallic Thermometer Factory, Jiangsu Zhaolong Electrics Co., Ltd. is a regional high-tech enterprise and a production base of temperature sensors and temperature control instruments. We have jointly developed and produced a series of thermocouples (thermal resistances) and temperature control electronics with numerous R&D institutions and academies in Shanghai. These products are salable throughout the country and the world, offering an advantage in cost performance. Our products have a renowned reputation in the market and win customers' trust due to their excellent performance, attractive appearance, high reliability, advanced technology, and good cost performance.
With strong technical development team and patent results, we can undertake business for normal and special specifications, and can design & install various large-scale and small-scale automatic temperature control boxes and temperature control rooms and remote monitoring temperature control systems for customers.
If you have ever compared two thermocouples on the same pipe and watched them disagree by a few degrees, the sensor tip probably was not the problem. More often, the answer sits at the other end of the loop, in the term...

READ MOREAs a Bimetallic thermometer manufacturer in Jiangsu, China, Jiangsu Zhaolong Electrics Co., Ltd. designs and produces mechanical and digital bimetallic thermometers for direct on-site temperature indication. Since 2005, we have operated a 33,300 m² production base with more than 100 employees and a technical team focused on temperature sensors and temperature control instruments. Our bimetallic thermometer range serves process plants, pipelines, boiler houses, storage facilities, and OEM machinery where operators need a dependable local temperature reading.
The category is organized into two complementary product lines: Bimetallic pointer thermometer for purely mechanical indication and Bimetallic digital thermometer for clearer readouts and mercury-free replacement of older glass thermometers.
Both product lines use a bimetallic sensing element that responds to temperature changes without requiring external power for the pointer version. The digital line extends this concept with a more readable display and additional mounting flexibility.
Mechanical coiled bimetal helix drives a pointer on a dial. No batteries, no signal wiring, and no electrical components make it a straightforward choice for routine process monitoring.
Developed from our WST-101/102 series, this digital display instrument is practical for medium- and low-temperature on-site measurement of liquids and gases. It is designed as a direct replacement for bimetallic, pressure-type, and glass mercury thermometers, without mercury damage risk.
| Product line | Construction | Typical fit | Configuration notes |
|---|---|---|---|
| Bimetallic pointer thermometer | Coiled bimetal helix, pointer dial | Boilers, pipelines, tanks, heat exchangers, machinery | Custom stem length, 1/2 thread, axial/radial, 304 stainless steel |
| Bimetallic digital thermometer | Digital display with bimetallic sensing system | Medium/low temperature liquids and gases, mercury thermometer replacement | Panel 50/100 optional, M27*2, depth custom default 150 mm, axial/radial |
| WST-101/102 series | Latest digital liquid thermometer development | On-site temperature measurement in industrial plants | No mercury, easy reading, robust construction, direct replacement for pointer bimetallic and pressure-type thermometers |
Bimetallic thermometers are widely used in chemical processing, natural gas, petrochemical, power, metallurgy, building materials, mechanical industry, food machinery, and daily chemical production. They provide quick visual confirmation during routine inspections, maintenance checks, and process monitoring.
We supply standard configurations for pipes, tanks, and equipment surfaces, as well as custom designs for OEM projects and special plant layouts. Our project team can also design and install automatic temperature control boxes, control rooms, and remote monitoring temperature control systems around our temperature instruments.
We implement full-process quality supervision with a modern production line and advanced testing methods. Jiangsu Zhaolong Electrics Co., Ltd. holds ISO9001:2015 quality system certification, CE certification, and multiple invention and utility patents related to temperature measurement.
Our laboratory is equipped for calibration over a temperature range from -200°C to +2000°C with resolution up to 0.01°C and temperature control within ±0.1°C. Each bimetallic thermometer is factory-tested before delivery, and we provide calibration service for instruments that require periodic verification. We back delivered products with a warranty period of up to 12 months against non-human damage and maintain spare parts supply for replacement needs.
To prepare a configuration and quotation, our engineering team works from the following project information:
For standard WST digital thermometers, our lead time is 5–7 working days for 50 pieces. Custom quantities and non-standard configurations are quoted with the project schedule.
The pointer model is a purely mechanical instrument with a dial and requires no power supply. The digital model gives a numerical readout and is designed for easier reading and mercury-free replacement of glass mercury thermometers. Choose pointer for simplicity and no-power installation; choose digital where a clear, unambiguous display is preferred.
Yes. Stem depth is customized to your installation point, with a default of 150 mm. Standard thread options include M27*2 on the digital series and 1/2 thread on pointer models. Other thread types can be evaluated against the application.
Both are available. Axial mounting is suitable for top or side installation where the dial faces the operator; radial mounting is used when the dial must be parallel to the pipe or tank. Our configuration team confirms the correct version from the site layout.
Each instrument is factory-tested before shipment. Our quality system is certified to ISO9001:2015, and relevant products carry CE certification. Calibration service and calibration certificates are available for instruments used in controlled processes.
For the WST digital series, standard delivery is 5–7 working days for 50 pieces. Custom lengths, special materials, and large quantities are scheduled individually and confirmed in our proposal.
Our portfolio also includes See Details for applications with different operating ranges, interfaces or integration requirements.
