Do you provide Live Tech Support?
Yes, we’re old school and still have real people answer our phones and respond to questions. We have training videos, quick-starts and your salesperson will do training and after all that, we’ll still answer the phone!
Can the sensors be calibrated in the field?
Absolutely! We recommend periodic user calibrations for TVOCs (PID sensor), but all of the sensors may be calibrated in the field with the appropriate reference gases, regulator and calibration cap (with the exception of Air Speed, Temperature, Formaldehyde and Differential Pressure).
Can I use my own device?
You can, with some caveats. You can use an Android or iOS devices with the free WolfSense Mobile software application to connect wirelessly via BLE to DirectSense II/XM Probes and WolfRadio-XM-equipped Particle meters. You can also use your own Windows PC or Laptop with a licensed copy of WolfSense LAP to connect DirectSense II/XM probes wirelessly or wired (USB) . What you can’t do is measure differential pressure or barometric pressure as those sensors are built-in to our AdvancedSense, Zephyr and WolfPack meters.
Can probes be left outside?
They are not designed for prolonged use outdoors but many customers use them to collect ambient air samples to compare to the indoor air, which is an important step in IAQ investigations. DirectSense probes and particle counters are not meant to be left unprotected in outdoor environments for extended periods but can be used within operational limits.
Can readings be sent to the cloud or our own internal platform?
Yes and yes. GrayWolf has a cloud platform called GrayWolfLive which allows your Wi-Fi enabled DirectSense probes, WolfPack XM’s and AdvancedSense XM’s to send data to our cloud server. From our server you can use our API to access your data, or if you prefer to host your own server, our probes and meters can post JSON directly to a URL you provide.
How often do the sensors need calibration?
Depends on the sensor! We recommend annual factory calibrations, at minimum. You can user-calibrate as often as you like in the field or in your own lab. Some sensors require frequent zeroing while others are stable for months. There are also a small number of sensors that should be replaced annually or biennially, but the majority of our smart sensors will last for years with re-calibrations.
And since they are smart-sensors, individual sensors can be extracted from the probe and sent back for replacement, upgrade or calibration without having to take the entire probe out of service.
Do you work with MacOS?
Not directly, but our meters can export readings directly to CSV format which can be read by Apple’s Numbers Spreadsheet (and Google Sheets for Android). Also, if you are using GrayWolfLive, you can access it from any computer with a web-browser which includes Macs!
Should the IAQ probes stay stored plugged in?
This is not necessary, but it’s perfectly fine to leave the DSII/DSXM Probes in their Charging Cradle for long term use or storage. The DSII/DSXM provides a trickle of current to support biased sensors and maintain the clock. If you know you will be storing it for a long time without power, we recommend charging it up full so it’s ready to go when you need it. More importantly, if storing the probe for a long time, store it in a clean and dry place, especially if a HCHO or VOC sensor is installed and allow enough time for probe warm up and sensor stabilization when you do turn it back on.
Should the AdvancedSense XM be stored plugged in?
This is not necessary. The XM will completely power down and will preserve its battery for long periods during storage. If you know you will be storing it for a long time, we recommend charging it up full so it’s ready to go when you need it as all devices will lose a little bit of charge over time to maintain the clock.
What is the effective sensing radius of the probe?
The DirectSense II/XM Probes are passive monitors. They are designed to measure the air immediately around the probe and the air that the probe passes through as it is carried around for inspections/ walk throughs and locating potential IAQ trouble spots. The DSII/XM Probe contains a small fan to move air immediately surrounding the probe through the smart sensor modules to prevent air from getting trapped or stagnant inside of the probe. A second micro fan moves air across the Temperature/Humidity sensor to cancel any heating effects of the electronics in the probe. For most applications, particularly for long-term monitoring, the general airflow in a room will be sufficient to ensure compounds reach the probe for detection. For locating potential sources, it is recommended that the probe be moved around in different zones for at least 90 seconds (most sensors have a T90 response <30 seconds but several are 90 +). Waving the probe through the air will increase sensor response.
