Grant manufactures a comprehensive range of robust, high quality temperature probes with a choice of sensor and in a variety of physical styles for use with Squirrel data loggers. In addition to the standard range of temperature probes Grant is able to customise probes for special applications.

Thermistors:
larger electrical signal for a given temperature change than other sensors,
fast response time,
high accuracy (± 0.1°C),
preferred sensor over the operating range -50 to +150°C,
long cable lengths possible without significant errors,
mini thermistors available for miniature/needle probes
Thermocouples:
suitable for temperatures from -25°C up to +250°C,
fast response time,
moderate accuracy (± 0.5°C),
suitable for a wide range of applications from delicate to heavy industrial
Platinum resistance:
suitable for temperatures from -50°C up to +250°C,
good accuracy (± 0.3°C),
good long term stability,
choice of Pt100 and Pt1000 sensors,
choice of 2 and 4 wire where compensation of cable resistance required,
Capacitive humidity and temperature probes
Rotronic HYGROMER™ with Pt100 sensor:
Operating range -40 to +85°C (-0.4 to +0.85V); 0 to 100% r.h. (0 to 1V),
sensors protected against dust and pollution,
fast response time: <0.7s (start-up 3s),
good long term stability,
robust polycarbonate housing,
accuracy (at +23°C): humidity ±1.5% r.h.,temperature ±0.3°C,
good long term stability: <1% r.h./year
