Red Liquid Glass Thermometer

• 30 cm glass thermometer body
• High-visibility red liquid column
• Graduated temperature scale
• Slim glass rod construction
• Suitable for direct-contact temperature measurement

• 0-100°C Measurement Range: Suitable for common farm, water and agricultural temperature monitoring applications.
• 30 cm Extended Length: Convenient for measuring liquids in buckets, tanks and other containers.
• High-Visibility Red Column: Red liquid provides clear contrast against the graduated scale for easier reading.
• Glass Construction: Traditional liquid-in-glass design provides simple and stable temperature indication.
• No Battery Required: Operates entirely through thermal expansion without electrical power.
• Simple Operation: Direct temperature readings without programming, charging or calibration controls.
• Low Maintenance: No electronic components or replaceable batteries are required for normal operation.
• Multi-Purpose Farm Use: Suitable for livestock facilities, water systems, feed preparation and general agricultural temperature checks.

• Livestock drinking water temperature checks
• Pig farm water-system monitoring
• Feed and liquid-feed preparation
• Milk and liquid temperature checks
• Farm environmental temperature monitoring
• Agricultural production and greenhouse use
• Laboratory and educational temperature measurement
• General liquid and material temperature testing

• Inspect the glass body for cracks or damage before each use.
• Place the sensing end into the material or liquid being measured without exceeding the specified temperature range.
• Allow sufficient time for the red liquid column to stabilize before reading the temperature.
• Read the scale at eye level to reduce parallax error.
• Avoid contact between the thermometer and the sides or bottom of hot containers when measuring liquids.
• Clean the glass surface after use with a suitable non-abrasive cleaning method.
• Handle carefully because the thermometer body is made of glass.
• Do not use the thermometer if the glass is cracked or the liquid column is separated.
• Store in a protective case or secure location away from impact when not in use.

Q: What is the temperature range of this thermometer?
A: The specified measurement range is 0°C to 100°C.

Q: How long is the thermometer?
A: The thermometer is approximately 30 cm long.

Q: Does it require batteries?
A: No. It is a traditional liquid-in-glass thermometer and requires no electrical power.

Q: Why is the liquid column red?
A: The red color provides strong visual contrast against the scale, making temperature readings easier to observe.

Q: Can it be used to measure water temperature on livestock farms?
A: Yes. It is suitable for routine drinking-water, liquid-feed and other farm temperature measurements within its specified range.

Q: Can it be used for ambient temperature monitoring?
A: Yes, provided the expected temperature remains within the 0-100°C measurement range and the thermometer is positioned safely.

Q: How should the temperature be read?
A: Wait for the liquid column to stabilize, then read the scale at eye level at the top of the red liquid column.

Q: What should I do if the thermometer is damaged?
A: Stop using it immediately if the glass is cracked, broken or the liquid column becomes abnormal, and replace the thermometer.
