Single gas clip-on personal monitor

Individuals need personal protection in hazardous areas at all times without adding extra bulky equipment, and the 03 Series can provide that kind of protection at an affordable price

Safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by CSA approval to U.S. and Canadian standards for Class I, Division 1, Groups A, B, C, and D atmospheres. Each 03 Series monitor is impact, dust, and water-resistant with an IP-67 rating. 

The GP-03, OX-03, CO-03, and HS-03 models are personal single-gas monitors designed for protection from exposure to combustible hydrocarbons, oxygen deficiency, hydrogen sulfide, or carbon monoxide.

this gas clip-on personal monitor is ideal for:

1. Hazardous material
2. Mining
3. Refineries/petrochemical
4. Water/wastewater treatment
5. Pharmaceuticals
6. Utilities
7. Chemical plants
8. Fire services

The O2, CO, and H2S versions can be operated continuously for at least 3,000 hours on (2) AAA-size alkaline batteries. The GP-03 operates for 35 hours on alkaline and 30 hours on rechargeable Ni-MH. The 03 models have 2 preset alarms that are user adjustable. Each version is also equipped with visual, audible, and vibration alarms as standard.

The replacement sensors are inexpensive, easily field replaceable, and are interchangeable with other popular RKI instruments like the GX-2009, GX-2012, and GasWatch 2. Sensors for LEL and O2 have a life expectancy of over 2 years. Sensors for H2S and CO have a life expectancy of over 3 years.

QUICK TIP:

Startup procedure

1. Press and briefly hold down the POWER MODE button. The backlight will turn on and all the display segments will turn on. Release the button when you hear a beep.

2. The vibrator vibrates and the alarm light flashes momentarily.

3. The initial startup screen depends on how Bump Fail Behavior is set.

4. If Cal. Limit Display is set to Off, proceed to Step 6.

5. If Cal. Limit Display is set to On (factory setting), the screen that appears next depends on how Cal. Limit Check is set

6. If Bump Test Limit Display is set to Off (factory setting), proceed to Step 8. 7. If Bump Test Limit Display is set to On using the 03 Series User Setup Program, the next screen will depend on how Bump Test Limit Check is set in Setup Mode or using the 03 Series User Setup Program.

8. The Date/Time Screen appears for a few seconds.

9. The Battery Voltage Screen appears for a few seconds

10.The display then indicates the following items for about a second each: • Full scale value • Warning setpoint (low gas alarm) • Alarm setpoint (high gas alarm)

11. If the GP-03 experiences a sensor failure during start up, the following screen will appear

12.If Auto Zero Adjustment is set to On (factory setting is Off), then the GP-03 will perform an automatic fresh air adjustment.

13.The GP-03 is now operating in Measuring Mode and monitoring for gas. The Normal Operation Screen appears and the instrument beeps once.
