Instrument Name: YSI Tele-Thermometer
This piece consists of a brown plastic box with a black handle. On the front of the box is a scale marking a range of temperatures from 0 to 50 degrees celsius, with a red needle indicating the measured temperature. To the right of this scale is a metal toggle switch marked “ON” and a black plastic knob marked “ADJ TO RED LINE”. To the left of the scale are two jacks marked “RECORDER,”, one framed in red and the second in black. A third jack is marked “PROBE” and a rubber-coated gray cord is plugged into it. At the end f this cord is a shorter white wire that makes up the sensor for the thermometer. The gray cord is approximately 353cm long. When the toggle switch is flipped on, the instrument functions to measure the temperatures to which the white sensor is exposed.
Primary Materials: Plastic, metal, rubber
A label on the top surface of the box: “Department of zoology 5604 11 Physiology Laboratory”
On the same surface, handwritten in marker: “SWITCH OFF AFTER USE”
On the front surface, labelling the switches and jacks: “ON” “ADJ TO RED LINE” “RECORDER” “PROBE” “USE YSI 400 SERIES PROBES ONLY”
On the temperature scale: “YSI TELE-THERMOMETER” “F” with a measure of temperatures 40 to 120 in 10-degree increments; below this, “C” with a measure of temperatures 0 to 50 in 10-degree increments.On a logo to the bottom right of the scale: “YSI”
On he back surface of the box: “Yellow Springs Instrument Co., Inc. Yellow Springs, Ohio Model 434TD Serial 50604″
Oh a label on the bottom surface: “Q. C INSP. 1 5″
On the plug of the gray cord: “LN3431″
Dimensions (cm): Length =20, Width =7.5, Height = 17
This instrument measures temperature as detected by the white sensor at the end of a long cord
Very good: a few minor scratches on the plastic box, The instrument is functional; presumably it is powered by an internal battery.
