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.
Temperature Probes (TLp module)
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.
Light Probes (TLp module)
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.
It uses an Ion Selective Field Effect Transistor (ISFET),
with built-in temperature sensing and compensation, giving
it excellent long-term stability for extended time
measurements. The probe provides temperature compensated
readings from 1° C to 60° C. Temperature and pH can be
displayed simultaneously.
The MultiFunction pH Probe uses a high-grade polymer in
the tip, rather than glass, which allows for more rugged
use--dropping and rough handling have no ill effects. The
probe can be used with non-liquid substances such as soil,
peanut butter, jelly, etc., and can even be inserted into
a piece of fruit. The probe is easily cleaned with a
toothbrush.
The MultiFunction pH Probe is solid state, using an
EPA-approved method, and stores in an unbreakable package.
The probe requires very small amounts of samples for
measurement and is ideal for micro-chemistry or measuring
solids. It can measure the pH of a single drop of a
substance. Normal life is approximately three to five
years.
Rugged, non-glass, solid-state electronics with fast
response time
