The J405 is designed to be easy to operate for quick and accurate analysis of mercury vapor levels.
Key Features
- Much lower detection levels than the previous Jerome® models
- 3.5" (9 cm) backlit display, showing everything you need to be confident in the instrument, including 5/8" (1.6 cm) tall character readout, battery charge indicator, and sensor saturation percentage
- Choice of units for results: micrograms per cubic meter (μg/m3) (default) or milligrams per cubic meter (mg/m3)
- Easy to understand diagnostic and error detection
- Auto zero bridge adjustment
- Updated electronics including 24-bit a/d conversion and on-board storage for 20,000 samples
- Controlled temperature film heat ensures the sensor removes all mercury and returns to its original state
- The Jerome® J405 can be operated for 24 hours from the internal 12V battery source or it can be operated using the external AC power supply/charger
Display Range
- 0.5 μg/m3 to 999 μg/m3
- 0.001 mg/m3 to 0.999 mg/m3
- Sample values below 0.5 μg/m3 or 0.001 mg/m3 will be recorded and displayed as 0.00 μg/m3 or 0.000 mg/m3 respectively by the J405. Sample values above 999 μg/m3 (0.999 mg/m3) will be recorded and displayed as “High Concentration.”
