Clinical Probes

		RET-1   Rectal probe for humans, neonatal rabbits, and larger animals. Flexible, vinyl covered, soft tipped. Does not cause discomfort. Max. Temp. 90°C. Time constant 5.0 secs. 5 ft. lead. Isolated.
		OT-1   For fast reading oral use. Ball-tipped stainless steel shaft,  stainless handle. 5 ft. lead. Max. Temp. 125°C. Time constant 0.8 secs. Not isolated.
		DSP-1  Disposable sterile sheaths for use with OT-1 and RET-1, per 1000
		SST-1  Skin Surface probe, to be taped on.1/4" dia. 10 Kt. gold  sensor disc, 5 ft. lead. Max. Temp. 90°C. Time constant 0.15 secs. Not isolated.
		SST-2  as SST-1 but with plastic handle. Isolated.
		ESO-1  Esophageal probe. Flexible vinyl covered 1/8" dia. Max. Temp. 90°C. Time constant 5.0 secs. 5 ft. lead. Isolated.

Time constant is defined as the time required to reach 63 % of final temperature in liquid. An accurate reading is obtained when the reading stops changing, typically 5-10 time constants.

Maximum Temperature refers to intermittent use of a probe. When probe is used for continuous measurements, max. temp. should be reduced by 25 % unless specified.
