Our on-line question-and-answer part number generator simplifies the selection of product options. A link to the part number generator is in the Product Links section above.

Action Level Options

Alarm level specified as "PK-Gx-Annn", where:
  "x" is the target gas: H / M / P / C
  "nnn" is alarm conc./resolution
  EG: Hydrogen 10,000 PPM is "PK-GH-A100"
  Note: 10-75% of sensor range only.
Warning level specified as "Wpp", where:
  "pp" is percentage code.
  Percentage code is 20-80% of alarm level

Calibration Options

Devices can be ordered with & without the offset button & span trimpot. We recommend fixed calibration for high vibration and tamperproof applications. Field access to calibration values is securely available via PK-Port.

Error Handling Options

1. Audio-visual indication of errors [E1]
2. Errors trigger alarms (fail safe) [E2]

Overdose Handling Options

1. Failure to hypersensitivity [X1]
2. Failure to persistent error state [X2]

Output Signal Option

1. TTL - Norm.-high, Auto (self-clearing) [O1]
2. TTL - Norm.-low, Auto (self-clearing) [O2]
3. TTL - Norm.-high, Latch (Button reset) [O3]
4. TTL - Norm.-low, Latch (Button reset) [O4]

   (Specify TTL signal to respond to warning    state, alarm state, or both.)

5. Proportional output - 0 to 5VDC [O5]
    0.5V safety offset (zero reading)
    200 steps of 20mV each
    Each step equals one resolution unit
  Relay Options

1. Relay not required [R0]
2. Normally-closed, Auto (self-clearing) [R1]
3. Normally-open, Auto (self-clearing) [R2]
4. Normally-closed, Latch (Button reset) [R3]
