Thermometers are used to measure temperature. There are 4 types of thermometers used in line probe assay (LPA) laboratories:

Electronic Max-Min Thermo-Hygrometer

It monitors the temperature and humidity, and has the following features:

Glass Alcohol Thermometer

It is used for monitoring temperature of refrigerator, incubator, Walk-in Incubator (WII) and Walk-in Cold room (WIC). It has the following features:

Digital Maxima-Minima Thermometer:

Resolution: 0.1°C
Accuracy: ± 0.1°C
Precision: ± 0.2 % full scale
Flexible probe (Preferably K type) Thermocouple, waterproof & Heat resistance cable/probe
Measuring frequency: 3 measuring per second
Display: Digital LCD display

Digital Maxima:

Measuring range: -100°C to + 60°C
It is used for calibration for -80 deep freezer, -20 deep freezer, refrigerator, WIC

Digital minima:

Measuring range: 0°C to +300°C
It is used for calibration for Incubator, Oven, WII, Autoclave, GT Blot, Twincubator, Thermocycler

Dial Spring Thermometer:

It is used for calibration for -80 deep freezer, -20 deep freezer, refrigerator, WIC.

Temperature Range: +50°C to +300°C
Accuracy: +1% Full Scale. Reading stabilization within 1 min
Casting Material: Optically clear strong glass cover with stainless surface mount (highly resistance to corrosion)
Type: Bimetallic dial thermometer
Easily readable centigrade scale

Maintenance:

Verify that all thermometers in the laboratory are accurately reflecting the temperature
Always use calibrated thermometers
Thermometers that are in use should be calibrated every 6 months and documented
