Description

“Ji” Japsin Instrumentation Bi-Metal Dial Thermometer – 4″ Dial, 0–100°C Range, 12″ Stem, Bottom Entry, Stainless Steel Build

The “Ji” Japsin Instrumentation Bi-Metal Dial Thermometer is engineered to deliver consistent and reliable temperature measurement in industrial and commercial environments. Featuring a 4″ (100 mm) dial, an extended 12” stem length, and a direct bottom entry mounting, this temperature gauge provides easy readability and accurate results for both process monitoring and equipment diagnostics.

Designed with a 0 to 100°C range, this thermometer is ideal for a wide array of general-purpose and industrial applications, including HVAC systems, water tanks, food processing, boilers, chemical plants, and more. Its bi-metallic sensing element provides a fast response to temperature changes, ensuring real-time monitoring.

With a 1/2″ BSP (M) process connection, a robust stainless steel case, and SS wetted parts, this gauge is resistant to corrosion and built to withstand harsh conditions, making it a dependable choice for long-term operations.

Precision in Every Reading

The Ji Japsin Bi-Metal Dial Thermometer is built around a bi-metallic sensing element that offers accurate and fast-response temperature monitoring. The design works on the principle of thermal expansion—two dissimilar metals bonded together expand at different rates when exposed to heat, causing the pointer to rotate and display the temperature. This system is extremely reliable and requires no power supply, making it ideal for remote and passive applications.

With a measurement range of 0 to 100°C, this thermometer is ideal for low-to-moderate temperature monitoring across industries like pharmaceuticals, HVAC, food and beverage, water treatment, and general manufacturing.

Clear and Bold Dial Design

The 4” dial is designed for high visibility, featuring a white background with black bold numerals and a red or black pointer (as per availability), providing quick and clear temperature reading without eye strain. This large face improves safety and efficiency in fast-paced or high-temperature industrial settings.

The dial is sealed in a weather-resistant stainless steel case that offers both strength and aesthetic durability, allowing the gauge to remain legible even in dusty or humid conditions.

Extended Stem for Immersion Applications

The 12” stem length with 10 mm outer diameter allows the thermometer to be inserted deeper into tanks, pipelines, or vessels, enabling a more accurate core temperature reading—especially in large fluid volumes or gas chambers. The stem is built from stainless steel, offering excellent corrosion resistance, chemical durability, and hygiene for use in food-grade and chemical environments.

Bottom Entry Mounting for Seamless Integration

The direct mounting bottom entry configuration with a 1/2” BSP (M) thread allows straightforward installation into standard industrial process connections. The thermometer can be fixed directly into pipelines, vessels, or panels without the need for complex adapters.

This installation style is perfect for vertical process pipelines or tanks where downward immersion is required.

Applications Across Industries

The “Ji” Japsin Instrumentation Bi-Metal Dial Thermometer is suitable for a wide range of use cases:

• HVAC Systems: Monitor return or supply air temperature for building automation.

• Boilers & Heat Exchangers: Keep track of operational temperatures to ensure safety.

• Food & Beverage Industry: Monitor process temperatures in cooking, fermentation, or packaging lines.

• Water Treatment Plants: Control temperature in reservoirs, filtration units, and piping.

• Chemical Plants: Suitable for non-corrosive liquid and gas environments.

• Pharmaceuticals & Biotech: Reliable monitoring during formulation and mixing.

• Agriculture & Greenhouses: Keep track of environmental conditions for crops or livestock.

Installation Tips

• Use a Thermowell in high-pressure or corrosive environments to protect the stem and extend lifespan.

• Thread Sealant: Always apply PTFE tape or appropriate thread sealant to the process connection to avoid leakage.

• Mount Vertically: Install in a vertical upright position to ensure proper functionality and easy visibility.

• Avoid Over-Torque: Do not overtighten during installation as this may damage the stem or thread.
