Orion Star A Handheld Meters

From $582.95
List Price From $654.00

Thermo Scientific Orion Star A Handheld Meters provide complete portability without sacrificing testing accuracy. IP-67 waterproof housing and protective plug covers prevent corrosion, even in difficult testing environments. The bright, backlit displays clearly displays results in rain or shine. The ergonomic design features a recessed grove in the back and a textured keypad to ensure a secure grip, even with gloved or wet hands. Choose from three meter types:

A100 Series Meters (A121, A122, A123) are single-parameter meters suitable for basic testing needs. They feature a 7-button keypad and English language prompts. Meters hold up to 50 data points and display both temperature (ºC and ºF) and calibration.

A200 Series Meters (A221, A222, A223) are single- or dual-range parameter meters capable of storing up to 1000 data points. They feature an expanded RDO range (up to 50 ppm) and a real-time clock. Meters have dual-probe capacity – RDO for standard readings and polarographic for faster DO readings. Other features include DIN pH buffer curves and mV values with pH readings. The multilanguage interface supports English, Spanish, French, Italian, German and Chinese.

A300 Series Meters (A321, A322, A323, A324, A325, A326, A329) are dual or multiparameter units with additional datalogging capabilities and security features. The informative display includes information about electrode status, time, date, sample ID, user ID, and calibration points. Stability and averaging provide flexible options for data. Units include up to 5-point calibration; calibration editing and log function are automatic. The non-volatile memory holds up to 5000 data points; units also store up to 10 methods to allow or customized procedures.

 

Meters are available with a variety of test parameters:

Meters with pH measurement feature automatic calibration for USA/NIST and DIN buffers (3-point calibration for A100 Series meters; 5-point calibration for A200 and A300 Series meters).

Meters with conductivity include readings for conductivity/TDS, temperature (in ºC or ºF), meter mode and power source. Meters include both a selectable cell constant and reading reference temperature to ensure accurate results. A200 and A300 Series meters include a choice of practical salinity or natural sea water curves for salinity readings, plus linear or ISO/EN 27888 curves for TDS.

Meters with dissolved oxygen include DO reading in mg/L or % saturation, temperature (in ºC or ºF), meter mode, and power source. Automatic temperature, manual salinity input, and manual barometric pressure compensation (automatic compensation on A200 and A300 Series) ensures an accurate result. A100 Series meters have two calibration options: water-saturated air method or a Winkler titration; A200 and A300 Series meters can be calibrated using water-saturated, air, air-saturated water, Winkler titration or zero-point calibration. These meters can also be used with AUTO-STIR polarographic DO probes for faster readings.

All meters include a universal 100-240 VAC AC adapter. Meters can also be powered by four AA batteries (not included). pH electrode input is BNC; ATC probe input is 8-pin mini DIN.
