Connect the sensor following the steps in the Getting Started section of this user manual.

• Do not put directly into flames.
• Do not touch the tip to a hot plate.
• Do not immerse the handle in liquids above the stainless steel shaft.
• Do not wrap the cable tightly around the sensor for storage.
• Avoid prolonged exposure to acids and bases.
• Always wash the probe thoroughly after use.

The Vernier EasyTemp does not need to be calibrated. It is calibrated extremely well before it ships.

Temperature range	–20 to 115°C
Maximum temperature that the sensor can tolerate without damage	150°C
Resolution	0.07°C
Accuracy	±0.05°C
Response Time	4 s (to 90% of full reading in water)

Overheating the sensor is the most common cause for this sensor to break. When used in chemistry labs, students will sometimes lay the sensor on a hot plate and effectively “cook” the unit. Unfortunately, these causes of breakage are considered misuse and are not covered by our warranty. In our experience, repair is not possible for this type of damage.

Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.

The EasyTemp probe is constructed of high-grade stainless steel, which provides a high level of corrosion resistance for use in the science classroom. Here are some general guidelines for usage:

1. The probe handle is molded plastic. While this material is chemical resistant, we recommend that you avoid submerging the probe beyond the stainless steel portion.
2. The stainless steel portion of the probe can be left continuously in water at temperatures within the range of –20°C to 115°C. Continuous usage in saltwater will cause only minor discoloration of the probe, with no negative effect on performance.
3. You can leave the probe continuously in most organic compounds, such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, n-hexane, lauric acid, paradichlorobenzene, phenyl salicylate, and benzoic acid. The probe should not be left in n-pentane for more than one hour.
4. The probe can be left in strong basic solutions, such as NaOH, for up to 48 hours, with only minor discoloration. We do not recommend usage in basic solutions that are greater than 3 M in concentration.

5. The chart provides the maximum length of time recommend for probe exposure to some common acids. Probes left in an acid longer than these times may bubble and/or discolor, but will still be functional. We do not recommend probes be left to soak in any acid longer than 48 hours.

   Maximum acid exposure time
   1 M HCl	20 min
   2 M HCl	10 min
   3 M HCl	5 min
   1 M H2SO4	48 hours
   2 M H2SO4	20 min
   3 M H2SO4	10 min
   1 M HNO3	48 hours
   2 M HNO3	48 hours
   3 M HNO3	48 hours
   1 M CH3COOH	48 hours
   2 M CH3COOH	48 hours
   3 M CH3COOH	48 hours
   1 M H3PO4	48 hours
   2 M H3PO4	48 hours
   3 M H3PO4	48 hours
