Frequently asked questions
Common questions about THERMO SCIENTIFIC from 3G Electric.
What is the measurement range of the Thermo Scientific 9104APWP pH electrode?
The 9104APWP glass pH electrode measures across the full 0 to 14 pH range. It has a rugged tip shape and a double junction, which helps reduce contamination in samples containing sulfides, proteins, or heavy metals. The electrode terminates in a BNC connector and includes a 1 m cable. A 60 mL bottle of electrolyte is supplied with the unit. This electrode is suitable for both laboratory and industrial pH testing where a durable, general-purpose probe is required.
What are the connector and cable specifications for the Thermo Scientific 927007MD temperature probe?
The 927007MD temperature probe has a Mini-DIN connector and a 1 m cable. Its overall diameter is 1/4 inch. The probe body is epoxy, and the tip is flat, making it appropriate for surface-contact or immersion measurements. The operating range is 0 to 80 °C. This probe is used with Thermo Scientific meters that accept a Mini-DIN input for temperature measurement.
What parameters can the Thermo Scientific STARA3220 handheld meter measure?
The STARA3220 measures conductivity, salinity, temperature, and total dissolved solids. Its conductivity range extends up to 200 mS/cm, with an accuracy of 0.5% of reading ±1 digit. The meter includes automatic temperature compensation and a digital display. It is a handheld unit intended for field or bench use where multiple water-quality parameters need to be checked. The STARA2220 is a similar model but rated to 3,000 mS/cm for higher-conductivity samples.
What water purity type do Thermo Scientific dispensing guns deliver?
The dispensing guns listed, such as part numbers 50136505, 7601040, and 50136494, are configured to deliver Type I ultrapure water. Type I water is used for reagent preparation, buffer dilution, and analytical instrument feed. These dispensers are compatible with specific Thermo Scientific water purification system models, including 50136169, 7201031, and 50136153. Compatibility should be verified against the model number of the existing purification unit before ordering.
What is the difference between the Thermo Scientific STARA1220 and STARA3220 conductivity meters?
The STARA1220 measures conductivity, total dissolved solids, and temperature, with a conductivity range up to 200 mS/cm and accuracy of 0.5% of reading ±1 digit. It includes an electrode stand. The STARA3220 measures conductivity, salinity, temperature, and total dissolved solids, also up to 200 mS/cm with the same accuracy. The STARA3220 adds salinity as a measured parameter. Both are handheld digital meters with automatic temperature compensation. Selection depends on whether salinity measurement is required.
