Care and Maintenance
Probe Chemical Tolerance: The stainless-steel probe body is constructed from
grade 316 stainless steel. This high-grade stainless steel provides a high level of
corrosion resistance for use in the science laboratory. Here are some general
guidelines for usage:
l
The probe handle is constructed of molded plasticized Santoprene
®
. While
this material is very chemical resistant, we recommend that you avoid
submerging the probe beyond the stainless steel portion.
l
Always wash the probe thoroughly after use.
l
The probe can be left continuously in water at temperatures within the range
of –20°C to 330°C. Continuous usage in saltwater will cause only minor
discoloration of the probe, with no negative effect on performance.
l
You can leave the probe continuously in most organic compounds, such as
methanol, ethanol, 1-propanol, 2 propanol, 1-butanol, n-hexane, lauric acid,
paradichlorobenzene, phenyl salicylate, and benzoic acid. The probe should
not be left in n-pentane for more than one hour.
l
The probe can be left in strong basic solutions, such as NaOH, for up to
48 hours, with only minor discoloration. We do not recommend usage in
basic solutions that are greater than 3 M in concentration.
l
The chart provides the maximum length of time we recommend for probe
exposure to some common acids. Probes left in an acid longer than these
times may bubble and/or discolor, but will still be functional. We do not
recommend probes be left to soak in any acid longer than 48 hours.
Connecting via USB
Connected and charging
Blue and Green LED solid when sensor is con-
nected to Graphical Analysis via USB and unit
is charging. (Green LED is obscured by the blue
one.)
Connected, fully charged
Green LED solid when sensor is connected to
Graphical Analysis via USB and the unit is fully
charged.
Charging via USB,
connected via Bluetooth
Blue LED is solid and green LED is flashing, but
the green flashing LED looks white because it is
overwhelmed by the blue.
Identifying the Sensor
When two or more sensors are connected, the sensors can be identified by
tapping or clicking Identify in Sensor Information.
Using the Product
Connect the sensor following the steps in the Getting Started section of this user
manual.
Important:
When using this sensor, keep in mind that important electronic
circuitry is built into the handle of the probe. For optimal accuracy of the RTD,
keep the handle of the probe from warming above 40°C (104°F). If necessary,
shield the handle from high-temperature sources using aluminum foil or other
shielding material.
Calibration
Go Direct Wide-Range Temperature will never need to be calibrated. Each
probe is carefully calibrated before it ships, and this unique calibration is stored
on the sensor.
