Animal Rectal Probes (Type T Thermocouple)

WPI offer a range or rectal probes for use with rats, mice and small animals.

Options

Order code	Description
RET-2	Ideal for rectal temperatures in rats to measure core temperature. Accurate to 0.1°C Smooth ball tip Stainless steel shaft - 1'' long, 0.059'' diameter Tip diameter 0.125'' 5' lead length Time constant 0.8 seconds Not Isolated
RET-2-ISO	Ideal for rectal temperatures in rats. In addition to the features of RET-2 it offers: An isolated sensor (can be used with monitoring equipment where electrical interference from other electrodes may be present) Reinforced strain relief for applications where probe is in more frequent use
RET-3	Ideal for rectal temperatures in mice to measure core temperature. Accurate to 0.1°C Smooth ball tip Stainless steel shaft - 3/4'' long, 0.028'' diameter Tip diameter 0.065'' 5' lead length Time constant 0.5 seconds Not Isolated
RET-3-ISO	Ideal for rectal temperatures in mice. In addition to the features of RET-3 it offers: An isolated sensor (can be used with monitoring equipment where electrical interference from other electrodes may be present) Reinforced strain relief for applications where probe is in more frequent use
RET-4	For small animals (mice) Flexible polyurethane sheath with smooth rounded tip Tip diameter Outside dia. nominal 0.032'' (max. at tip 0.04'') 3' lead length Time Constant 0.18 seconds
RET-5	For very small animals (neonatal mice) Flexible polyurethane sheath with smooth rounded tip Tip diameter Outside dia. nominal 0.024'' (max. at tip 0.03'') 3' lead length Time Constant 0.12 seconds

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 intermit tent use of a probe. When probe is used for continuous measurements, maximum temperature should bereduced by 25%.
