Temperature, Light & pH (TLp) Module 57F7925 ![]()
A high-resolution interface module that supports the three most commonly used classroom probes: temperature, light and pH. This module supports up to three temperature or light probes and one pH probe. When used with the TLp module, these probes can measure temperature with 0.05° C resolution and 1° C accuracy. The probes feature a solidstate current output temperature sensor, 1.5 meter cable, come pre-calibrated and are waterproof Standard Temperature Probes 84F9106 (TLp module) A fast 0.14 second (in water) time constant with a temperature range of -40 to 105°C. For use in air, water or other non-corrosive liquids. Extended Temperature Probe 84F9107 (TLp module) Jacketed in a stainless-steel tube with a Teflon cable for use in harsh environments over an extended temperature range of -55 to 150°C. Time constant in water is 1.2 seconds. When used with the TLp module, these probes deliver precalibrated, high accuracy light measurements using a solid state photodiode with no light hysteresis, minimal temperature sensitivity and full range linearity. The probes feature a multi-functional package that provides a 1/4-20 tripod mount, flat mounting surfaces and a 1.5 meter cable. The probes are waterproof. Both light probes include 5 filter holders for implementing custom attenuators or response curves. Radiometric Light Probe 57F7930 (TLp module) A response curve that extends from 400 to 950 nm and calibrated to measure light intensity in Watts per meter2 . Intensity range is 0 to 100 W/m2 with a resolution of 0.001 W/m2 . Photometric Light Probe 57F7929 (TLp module) A response curve that closely matches the human eye, and calibrated to measure light intensity in lux. Intensity range is 0 to 100,000 (bright sun) lux, spectral range of 400 to 700 nm and a resolution of 1 lux. Temperature/Light Extension Cable PSL7100 (TLp module) Adds 10 meters to the reach of your
temperature and light probes. Perfect for outdoor
experiments performed from indoors, or anything else you
would like some distance from. Up to thirty extensions
(yes, that’s 300 m) may be connected in series. pH Probe 57F7928 (TLp module) A solid-state pH probe that uses an
EPA-approved method and provides a fast response, easy
storing probe in an unbreakable package. Built-in
temperature sensing allows simultaneous measurements of pH
and temperature. The probe requires very small amounts of
samples for measurement and is ideally suited for
micro-chemistry or measuring solids such as soil. The pH
range is 0 to 12 pH with a resolution of 0.01 pH. Accuracy
is 0.02. Normal life is approximately one to three years.
