• The probe consists of a thermistor whose resistance decreases nonlinearly with increasing temperature. The measured resistance is converted to a temperature in °C, °F, or K.

• Yes

• The standard calibration is loaded with Logger Pro. A manual calibration can not be performed.

Preparing Temperature Probe for Use

• No special preparations are needed; just place the probe in the solution to be monitored and start collecting data.

Maintenance and Storage

• Rinse the probe with deionized water, wipe dry, and store as is.

Chemical Tolerance

• saline solution will cause minor discolorations over time
• most organic solvents are fine, although probe should not be left in n-pentane for more than one hour
• probe should not be left in basic solutions (<3 M for more than 48 hr; do not use in solutions whose concentration of base exceeds 3 M
• do not exceed the maximum contact time for the following acids (all other acids a maximum of 48 hr)
  • 1 M hydrochloric acid - 20 min
  • 2 M hydrochloric acid - 10 min
  • 3 M hydrochloric acid - 5 min
  • 2 M sulfuric acid - 20 min
  • 3 M sulfuric acid - 10 min
