- 3 user selectable output ranges to choose from: 0-10ppm, 0-50ppm, 0-100ppm
- Optional Ranges: 0-500ppm, 0-1000ppm, 0-2000ppm
The user selection of an output range simultaneously controls the analog output and the data logger so that both functions operate on the same range - Digital display: High resolution 3 ½ digit LCD. Reads full scale from 0.00ppm to 100.0ppm independently of output range selection
- Analog output signal: 0-1VDC represents the output range selected:
0-10ppm, 0-50ppm, 0-100ppm, etc. - Data logger: Logs data for 15 days @ 1 minute intervals, 30 days @ 2 minute intervals, etc. Represents the output range selected: 0-10ppm, 0-50ppm, 0-100ppm, etc.
- Power requirements: 115/230VAC to 12VDC battery charger. Rechargeable NiCad batteries, 350 hours continuous
- Minimum detection: 50ppb of H2S
- Repeatability: +/- 1% of range or +/- 0.2ppm of H2S, whichever is greater
- Operating temperature range: 25 to 115o F
- Diurnal temperature specification:
< +/- 3 % of scale over temperature range - 90% full scale response times for specified range: 0-100ppm <120 seconds @ 1.5SCFH
0-2000ppm < 120 seconds @ 1.5SCFH - Response to Methyl Mercaptan: 40% of actual concentration
- Response to Sulfur Dioxide: 18% of actual concentration
Area Classification: Designed for intrinsic safety for Class 1, Div. 1, Groups B,C,D - Inlet gas pressure: 0.5 to 150psig
- Gas connections: ¼" quick disconnect 316 S.S. compression fitting
- Wetted parts: 316 S.S. fittings, electroless nickel plated cellblock, gold plated contacts, acrylic flow meter and Viton O-rings
- Portable dimensions: 4.5"W x 9.5"H x 4.5"D
- Weight: 5 lbs.
