Tech Tip: Choosing a Temperature Probe for Chemistry Classrooms

Vernier offers several temperature probes for a variety of applications. Deciding which probe is best for you often depends on the types of experiments in your curriculum.

The Stainless Steel Temperature Probe is the most popular choice for chemistry classrooms. This probe has a range of –40°C to 135°C and can be used for all temperature experiments in Chemistry with Vernier, Advanced Chemistry with Vernier, Investigating Chemistry through Inquiry, and Vernier Chemistry Investigations for Use with AP* Chemistry.

The latest addition to our temperature probe family is the Vernier Go Wireless® Temp. Its durability, temperature range (–40°C to 125°C), and wireless capability make it perfect for a variety of uses. Students can view live readings, capture data in real time, and examine results. Go Wireless Temp works with iOS, Android, and LabQuest 2. See current compatibility details.

Do you need to monitor temperatures above 135°C? The Wide- Range Temperature Probe has a range of –20°C to 330°C and is designed to match the diameter of a typical glass thermometer. It can be used to monitor temperature for distillation experiments such as “Experiment 3: Determination of a Boiling Point: Simple and Fractional Distillation” in Organic Chemistry with Vernier.

The Thermocouple is a simple and rugged sensor designed to measure temperature in the range of –200°C to 1400°C. The wide range results in a lower resolution than other temperature sensors but it can be used to measure flame temperatures as high as 1400°C or liquid nitrogen temperatures at –196°C. One application for this sensor is to compare the temperatures of different flames (candles vs. Bunsen burner).

Sensor Range Accuracy
Stainless Steel Temperature Probe –40°C to 135°C ±0.2°C at 0°C, ±0.5°C at 100°C
Vernier Go Wireless® Temp –40°C to 125°C ±0.5°C
Wide- Range Temperature Probe –20°C to 330°C ±0.1°C at 0°C
Thermocouple –200°C to 1400°C ±5°C at –200°C to 0°C, ±2.2°C at 0°C to 900°C, ±15°C at 900°C to 1400°C
