| Type | |||
| Your choices are... | |||
| Dial Thermometer | Dial thermometers use a metal pointer on a circular scale to indicate temperature measurements. They have two main components: the needle and a temperature sensor. Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. | ||
| Glass Thermometer | The thermometer is made of glass and is filled with a liquid that reacts to temperature. | ||
| Digital Thermometer | Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display. Digital thermometers use RTDs, thermocouples or thermistor sensing components. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Technology Type | |||
| Your choices are... | |||
| Thermocouple Technology | Thermometer senses temperature using thermocouples. | ||
| RTD Technology | Thermometer senses temperature using RTDs. | ||
| Thermistor Technology | Thermometer senses temperature using thermistors. | ||
| Thermal Pyrometer / Detector | Infrared temperature sensors based on thermal technology may include: bolometers (variable resistance / thermistor), thermocouples / thermopiles, or pyrometers / pyroelectric detectors. | ||
| Red Alcohol Spirit Fill | Red alcohol is used in thermometers to indicate temperature. It is safer than mercury. | ||
| Mercury | Mercury is a liquid metal used in thermometers. | ||
| Other | Other unlisted, specialized, or proprietary thermometer. | ||

| Scale | |||
| Your choices are... | |||
| Fahrenheit | Dial/Display graduated in these units. | ||
| Celsius | Dial/Display graduated in these units. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Fahrenheit Scale | |||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| Fahrenheit Scale Divisions: | Scale division describes the smallest division of degrees that can be displayed on the thermometer. This affects the accuracy of the temperature reading. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| Celsius Scale | |||
| Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||
| Celsius Scale Divisions | Scale division describes the smallest division of degrees that can be displayed on the thermometer. This affects the accuracy of the temperature reading. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| Immersion | |||
| Your choices are... | |||
| Full Immersion | Thermometer needs to be fully immersed into media being measured. | ||
| Partial Immersion | Thermometer can be partially immersed into media being measured. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Length | |||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
Features

|
|
| ||
| General Features | |||
| Your choices are... | |||
| Small and made to carry in pocket. Has clip and/or sheath. | |||
| Probe | The thermometer has a probe. | ||
| Designed for use with Thermowell | The thermometer is designed for use with a thermowell. | ||
| Direct Immersion | The thermometer is configured for direct immersion in a solution. | ||
| Etched on Display | The display numbers are etched onto the thermometer | ||
| Printed on Display | The display numbers are printed on the thermometer. | ||
| Explosion Proof | A device that can withstand an explosion of gases within it and prevent the explosion of gases surrounding it due to sparks, flashes or the explosion of the container itself, and maintain an external temperature which will not ignite the surrounding gases. | ||
| Teflon Encapsulation | Used to monitor acids and other hazardous materials | ||
| Zero adjustment | Can reset zero point. | ||
| Laser Spot Aiming / Sighting | The device has a laser to show where measurement is being taken from. Laser is not used to sense temperature. | ||
| Automatic Emissivity Adjustment | The emissivity adjustment allows the device to detect only the emitted IR as opposed to the reflected or transmitted IR which would give a false temperature reading. | ||
| Protective Metal Sheath | The thermometer has a protective metal sheath. | ||
| Splash Proof, Watertight or Direct Immersion | Thermometer is rated for wash-down or wet environment applications. | ||
| Surface | The thermometer is configured to be used for surface measurements only. | ||
| Loop for String or Hook | The thermometer has a loop to connect a string or hook. | ||
| NIST Traceable or ASTM Certified | Subjected to certified testing procedures and documented. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
