Page 18: Smart Sensors
GrayWolf supplied “Smart Sensors” (an assembly comprised of specific sensor plus a permanently attached “Smart Board”) may be used in any DirectSense II probe and in any sensor slot (with the exceptions of NDIR which must be used in Sensor Slot 3, or the larger B series electrochemical sensors which must be used in slot 5). - Page 19 For optimum accuracy, it is advised to perform more frequent User calibrations of zero and/or span (dependent on application). GrayWolf makes the User calibration procedure simple and reliable. The software walks users through the calibration process. Calibration kits and appropriate reference gasses are available for shipment to most locations.
- Page 20 Over the “IAQ critical range” (350ppm to 2000ppm), based on GrayWolf data and long-term experience. Accuracy of +/-50ppm, +/-3% of reading. While GrayWolf recommends <2 week User cal intervals, years of customer feedback has indicated that User calibrations at 4 to 8 week intervals is satisfactory for most IAQ applications.

Page 52: Calibration Procedure
Performed with WolfSense LAP or DSII Configuration Tool September 2022 Calibration Procedure: Prior to attempting calibration, the DirectSense II probe should be powered on for a minimum of 30 minutes to fully stabilize for optimum results. 1. Select the parameter you wish to calibrate from the list of available sensors. - Page 53 Performed with WolfSense LAP or DSII Configuration Tool September 2022 5. Open the sensor hatch on the DirectSense II probe to expose the individual sensors. This is done by using a 2.5mm Hex driver to unscrew the screw on the top-back of the probe.
- Page 54 Note: User Calibrations will be immediately reflected in the readings of the DirectSense II probe when connected via cable or Bluetooth classic. The probe must be rebooted for the changes to take effect on readings sent over BLE (to the WolfSense Mobile app), Wi-Fi or OEM mode.
- Page 55 DirectSense II User Calibration Performed with WolfSense LAP or DSII Configuration Tool September 2022 After the calibration is complete, you can view the current settings in WolfSense LAP by selecting Probe Menu / Advanced Calibration / Display Active Cal.

When using the DSII Configuration Tool, select the CALIBRATE button, then the parameter to rest and press the FACTORY button. Typical Calibration Set Points and Gas Ranges To properly calibrate your DirectSense II probe, Gray Wolf recommends that the following gas and concentrations be used: Range Typical Set Point 0.5 ppm... - Page 57 In order for a molecule to be ionized by the UV lamp, the ionization potential (IP) must be lower than the energy of the UV lamp. GrayWolf utilizes a 10.6 electron volt (eV) lamp, so anything that has a higher ionization potential will not be detected. Major components of air such as nitrogen, oxygen, methane and carbon dioxide have a higher ionization potential then the UV lamp so they are not detected by a PID sensor, as can be seen in table below.
- Page 58 PID (TVOC) Sensor Guide Getting Accurate Readings with your GrayWolf VOC Probe The PID sensor is a very sensitive device. Proper care, storage, use and calibration of the PID sensor is required to yield optimal results for this product; whether your application is for low range applications, such as IAQ testing, or for high range toxic exposure screening.
- Page 59 (e.g. 110L) cylinders, generally have an uncertainty up to 100 ppb, although check with the specific manufacturer for clarification. Due to the uncertainty in the gas, GrayWolf recommends a positive set point of 100 ppb to account for the uncertainty of the gas. It should be noted that larger gas cylinders (e.g.
- Page 60 You can perform a bump-test of the sensor to verify its calibration by exposing the sensor to a known concentration of test gas. Using the regulator and hood supplied with the GrayWolf Calibration Kit, attach a cylinder of gas and start gas flow. After 5-10 minutes, the readings should stabilize.
- Page 61 If the target gas is the only compound present then there are two ways that you can measure for that compound: -The PID must have a known correction factor for the gas of interest. GrayWolf meters have a list of some VOCs with their correction factors listed onboard under Sensor Tips. In the cases of a known correction factor the compound can be displayed on the device.

® calibration edit point to 50-100ppb. The specification for the Scott HC Free Air supplied by GrayWolf guarantees less than 100ppb THC, and may not be precisely at zero. If the ambient conditions have very low TVOC concentrations, then it is possible that the ambient conditions are lower than the HC Free Air which will force a negative value, causing WolfSense to display zero. - Page 64 PID (TVOC) Sensor Guide Symptom: Solution: Readings will not stabilize. Be patient, especially with the PID sensor which is a very sensitive sensor. Try to avoid sudden temperature or %RH changes which will result in longer stabilization time. Each time the sensor is powered on, tiny amounts of contamination, which accumulate on the lens and lamp while the probe is powered down, are burned off.

Page 65: Sensor Response Test
PID (TVOC) Sensor Guide Sensor Response Test You can use readily available retail/commercial products to perform a simple response test of the PID sensor. This will verify the basic operation of the sensor but will not verify that it is properly calibrated. - Page 66 All GrayWolf total volatile organic compounds (TVOC) sensors are calibrated to isobutylene in the factory, so all readings must be compared against isobutylene. The GrayWolf PID utilizes a 10.6 eV lamp which means that it will illicit a response from any compound with an ionization potential (IP) below 10.6 eV.
