Overview
The Toray LC-860 is a high-function zirconia oxygen analyzer developed to control and monitor oxygen in the electronics industry, from trace ppm levels up to 100 % oxygen. It responds within 30 seconds, refreshes its own sensor when it detects deterioration and communicates over RS-232C.
- Measures 0.1 ppm to 100 vol % O2 on a 6-digit LED display
- 90 % response within 30 seconds
- Repeatability within ± 1 % of full scale
- Automatic sensor refresh during air calibration
- Self-diagnosis with 11 error types; device and concentration alarm outputs
- 0-10 V recorder output and RS-232C communication; portable or panel mounted
