REVIEW – You’ve in all probability heard that carbon monoxide (CO) is “the silent killer” as it’s colorless and odorless. You will get carbon monoxide detectors for the house, however what about one thing moveable? I received an opportunity to take a look at the TOPTES Guard-101, a 4 fuel monitor that matches within the palm of your hand.
What’s it?
The TOPTES Guard-101 is a chargeable handheld detection machine that screens 4 paramters: CO (carbon monoxide), LEL (decrease explosive restrict), O2 (oxygen) and H2S (hydrogen sulfide). It has user-adjustable alarms and alerts the person with mild, sound and vibration.
What’s included?
- TOPTES Guard-101 fuel monitor
- USB-C charging cable
- Clip-on sensor hood
- Directions
- Padded, arduous carry case

H2S measured at 1 PPM increments, vary 0-100 PPM
CO measured at 1PPM, increments, vary 1-1000 PPM
Design and options
The TOPTES Guard-101 fuel monitor is available in a hinged hardshell case. It’s not Pelican Case high quality, however ok.
There are three buttons on the entrance of the Guard 101, and a robust steel clip on the again.
Right here’s a closeup of that clip. It’s received a fairly ferocious grip.
There’s a USB-C port for recharging, coated by a rubbery flap.
Additionally included is a clip-on hood. I think about this is able to be good for a extra concentrated, pinpoint means of sensing, or air sampling through hose.
Meeting, Set up, Setup
The display lets you understand the TOPTES Guard-101 fuel monitor is charging when the USB-C is plugged in.
Whenever you energy up, the Guard-101 goes by a startup sequence. Right here, you may see the monitor flash its pink alert LEDs, a vibration alert, and an audible alarm.
Beneath is the primary display. There’s a bluish-white backlight that solely stays on just a few seconds after the final button press.
Within the higher left, EX shows the p.c LEL. The decrease explosive restrict (LEL) of any given fuel is the bottom level of focus (share by quantity) at which it turns into flammable within the ambiance. For instance, when measured between 5% and 17%, methane is ready to ignite. I have no idea if the Guard-101 is particularly calibrated for any particular fuel or gasses.
Within the higher proper, O2 shows the p.c oxygen by quantity.
Within the decrease left, H2S shows the extent of hydrogen sulfide in components per million (PPM).
Within the decrease proper, CO shows the extent of carbon monoxide in components per million (PPM).
One other display exhibits date, time, battery degree and firmware model.
There are a number of pages of menus.
Zero Alter, in keeping with the guide, permits you to add or subtract a set worth from the precise detected fuel focus. It’s used when calibration fuel is unavailable, however the displayed worth deviates from zero.
Cal Fuel is a password protected perform to be used by professionals to stop customers from unintentionally affecting common operation. The default password is “69”.
Alarm Set allows you to create set factors for every parameter when the monitor will provide you with a warning.
Alarm Rec allows you to view earlier occasions the alarm thresholds have been met.
Manufacturing unit Mode is one other password safety perform. Default Setting means precisely that.
Right here’s an instance of the Alarm restrict settings, and the Alarm Rec display.
Efficiency
To check the TOPTES Guard-101 fuel monitor, I took a propane torch which might launch the fuel if you partially squeeze the set off. Don’t do that until you’re in a well-ventilated space.
I positioned the nozzle subsequent to the monitor. I didn’t realize it on the time, however I forgot to unclip the fuel “hood”. It didn’t appear to have an effect on the efficiency.
I set the EX (%LFL) to enter alarm at simply 1%. I despatched puffs of propane close to the monitor inlet. On this clip, I captured the second (after about 10-15 seconds) when the monitor alerted to the alarm threshold. Discover the carbon monoxide (CO) additionally offers a studying.
What I like in regards to the TOPTES Guard-101 fuel monitor
- Cheap
- Rechargable
- Simple to make use of
What must be improved?
- No certificates of calibration
- Remember that sensors have a finite lifetime (as much as 5 years for O2)
Ultimate ideas
Should you want a fuel monitor that life and security will depend on, it’s your decision one thing with a certificates of calibration of some type. At this value level, the TOPTES Guard-101 monitor is certainly an inexpensive, straightforward to make use of instrument when you work in confined areas or round hazardous atmospheres.
