Thermometer – Solid Stem | Gopal Fire Safety

Gopal Fire Safety offers the OMSONS Liquid-in-Glass, Solid Stem Thermometer, a precision-built laboratory-grade instrument designed for accurate temperature measurement across a wide range of industrial and scientific applications. This premium Glass Thermometer is manufactured by OMSONS, a reputed brand known for consistent quality and ISI-compliant laboratory instruments. Built using durable glass and designed with a solid stem, the thermometer ensures clarity, precision, and long-term accuracy for demanding laboratory and industrial environments.

Overview and Use

The Glass Thermometer is an essential instrument used for measuring the temperature of liquids, solids, and gases. The OMSONS Solid Stem Glass Thermometer operates on a simple principle: as temperature increases, the liquid (typically mercury or a colored organic liquid) expands inside a narrow glass capillary, providing a clear, measurable indication along a calibrated scale.

This Glass Thermometer is used in laboratories, chemical processing plants, research institutes, food and beverage industries, and various manufacturing units that require precise temperature monitoring under controlled conditions.

At Gopal Fire Safety, this product is available in ready stock, enabling immediate dispatch through our WhatsApp order and inquiry system.

Applications

The OMSONS Glass Thermometer is versatile and can be used in:

• Chemical and pharmaceutical laboratories for solution and reaction temperature monitoring.

• Industrial process control and equipment calibration.

• Food and beverage industries for temperature verification during production.

• Educational and research labs for experiments and thermal studies.

• Environmental and water testing setups.

• Petroleum and refinery labs for product testing.

• HVAC, boiler, and machinery temperature inspection.

This wide applicability makes the Glass Thermometer a reliable, reusable, and accurate tool for both basic and advanced scientific use.

Construction and Design

The OMSONS Liquid-in-Glass Thermometer is manufactured from high-quality borosilicate glass, ensuring resistance to chemical corrosion, temperature fluctuations, and physical stress. The solid stem structure offers rigidity and better protection to the liquid column compared to capillary thermometers.

The thermometer’s clear white background with sharply printed markings ensures easy visibility and precise readings. Each instrument is thoroughly tested for calibration accuracy and leakproof sealing before leaving the factory.

Design Highlights:

• Solid stem design for durability and protection.

• Borosilicate glass for superior strength and clarity.

• Uniform capillary bore ensures even expansion and linear reading.

• High contrast scale markings for readability.

• Chemical-resistant and non-reactive materials for long service life.

Working Principle

The Glass Thermometer functions based on the thermal expansion principle. A sealed glass tube contains a measured quantity of thermometric liquid (such as mercury or colored alcohol). When temperature increases, the liquid expands and rises in the capillary; when it decreases, it contracts. The corresponding level against the graduated scale gives the temperature reading.

Key aspects that influence measurement accuracy:

• Uniform internal bore of the glass tube.

• Proper sealing to avoid gas bubbles or leakage.

• Stable environmental conditions during reading.

• Calibration against standard temperature scales (Celsius or Fahrenheit).

Each Glass Thermometer from OMSONS is designed to deliver reliable results under these principles, making it suitable for repeated laboratory use.

Calibration and Standards

The OMSONS Glass Thermometer complies with IP (Industrial Process) and ASTM standards, ensuring conformity with global measurement accuracy norms. Each unit is carefully inspected and tested against reference instruments to verify temperature scale alignment.

Calibration Details:

• Factory-calibrated at reference temperatures.

• Compatible with IP and ASTM calibration ranges.

• Optionally verifiable by certified calibration labs upon request.

Users are advised to recalibrate periodically or when used in extreme conditions to maintain consistent accuracy.

Advantages of Using OMSONS Glass Thermometer

• High Accuracy: Precision-calibrated for repeatable temperature readings.

• Durability: Solid stem and borosilicate glass reduce breakage risk.

• Chemical Resistance: Suitable for most acids, alkalis, and solvents.

• Low Maintenance: Simple cleaning and ready for repeated use.

• Easy Reading: Clear white scale with bold markings ensures visibility.

• Wide Range Compatibility: Ideal for labs, industrial plants, and educational setups.

Handling and Safety Guidelines

While Glass Thermometers are dependable, they require careful handling:

• Always hold by the stem, not the bulb.

• Avoid sudden temperature changes to prevent breakage.

• Clean after each use with mild detergent or alcohol wipes.

• Avoid direct flame exposure unless specified for high-temperature use.

• Store in a cushioned or lined case to prevent mechanical damage.

Broken glass thermometers should be disposed of safely, following local environmental and laboratory safety protocols.

Maintenance Practices

Proper maintenance ensures accuracy and longevity:

1. Cleaning: Rinse with distilled water after use.

2. Inspection: Check for cracks or liquid separation before readings.

3. Storage: Keep in an upright position at room temperature.

4. Calibration: Verify periodically with a reference thermometer.

Gopal Fire Safety recommends using foam-lined packaging and keeping the Glass Thermometer away from direct sunlight and high humidity.

Industrial Use-Cases

• Chemical Processing Plants: For monitoring exothermic and endothermic reactions.

• Food Industry: Ensuring accurate temperature control during pasteurization or cooking processes.

• Educational Laboratories: Teaching heat transfer and temperature measurement concepts.

• Water Testing: Measuring ambient and sample temperatures for accurate readings.

• Refinery and Oil Testing: Determining product stability through thermal consistency.

This makes the OMSONS Glass Thermometer a multipurpose tool trusted across industries.

Packaging and Delivery

Each thermometer from Gopal Fire Safety is securely packed in shock-resistant materials to minimize transit risk. Foam-lined boxes or cylindrical protective tubes are used to ensure the thermometer arrives intact. Bulk or institutional orders can be packed in custom cartons for safe long-distance delivery.
