The battery was a bit hard to locate, they don't carry that size everywhere. It works great.
USING WITH DI ONLY
Our initial design for Check-iT was for DI ONLY systems (note : all DI SYSTEMS can fail without notice, resulting in spots on windows, and unavoidable re-working)
Now, your Operator can take responsibility to check the TDS of his filtered water at any time during every working day, without costing their time, nor changing their normal work practices.
We recommend your Operators simply squeeze CHECK-IT each time before they raise their pole. it is simply 'SQUEEZE'n'READ' to get a reading in ppm.
REACH-iT's 'DRIVE-THRU CARWASH METHOD':
Our second design for CHECK-iT is for External Window Cleaners using REACH-iT's ‘Drive-Thru Carwash Method’.
The DRIVE-THRU CARWASH METHOD was developed to solve the high cost of DI RESIN when an Operator is using DI TANKS in HARD WATER AREAS (eg rural properties with well water). We learnt the magic path by observing that in our local Drive-Thru Carwash, our car is washed with tap water straight from the spigot, and we pay an extra buck for the ‘Spot-Free Rinse’ at the end.
Well - you can clean windows and frames the same way! Follow The Reach-iT TECHNIQUE with CONSTRUCTOR BRUSH with HYDRO-BLADE to effect a complete clean of all the windows on the building USING TAP WATER. Now - all the windows are 'clean', except they will have spots on the windows - but it is ONLY from the minerals in the tap water, as the tap water dried.
To remove these spots, simply connect your DI TANKS to your water supply, turn on the water, and wait for the hose and tube to flush the tap water out, and the pure water in, so you can start rinsing spot-free. - How do you know if the water at your brush is spot-free?
Now just RINSE THE GLASS with your spot-free rinse - one up-&-down stroke only on any window surface (it may be 203 stroke actions to clean any one window, moving across each window, and from window to window,
In less than 10 seconds per window you will effect a SPOT-FREE RINSE. The DI water will remove the minerals from the tp water, and leave your customers windows wet, but when this water dries, it will dry spot-free.
This method preserves your DI RESIN by using it ONLY for the critical part of the cleaning job - the spot-free rinse phase! 10 SECONDS PER WINDOW!
KNOW WHEN TO UPGRADE TO RO-DI
The 3rd design for CHECK-iT is to help you know when to choose to upgrade your system from DI ONLY to RO-DI :
WHEN TO STAY DI ONLY:
If your water from the spigot shows GREEN or ORANGE, you never need to upgrade to RO-DI unless you are running very high volume of water like a pure water refill station in your shop or running multiple vehicles.
WHEN TO UPGRADE TO RO-DI:
If the red light is lit (TDS <150ppm), then you MAY consider to upgrade to RO-DI. Basically, the upgrade will cost you around $2000 (compared to $200 for DI ONLY) for a high quality high-flow RO-DI unit, with replaceable, non-proprietary filters. Bought from a manufacturer with integrity, an RO SYSTEM will save you 90% of your annual DI COSTS.
For example, If you are spending $50 per week on DI RESIN in Los Angeles, California, its $2000 a year .. and a no brainer to upgrade. However, if you are spending $30 a week in Buffalo, New York with a 35 week season, your DI RESIN COST is around $1000 a year, and upgrading to RO-DI is worth considering, but not compelling.
RO is not the 'Holy Grail' for window cleaners - it needs to be a Business Decision - the performance of RO MEMBRANES changes under many variable conditions, so don't underestimate the convenience of DI ONLY, and The DRIVE-THRU CARWASH METHOD.
If you are thinking of choosing an RO-DI SYSTEM, have a look at REACH-iT FLOW (click here).
WHERE TO POSITION CHECK-iT:
We designed CHECK-iT to connect to RHINO-TUBE, or any 5/16" (8mm) tube. We recommend you locate CHECK-iT just under the brush, secure to your pole, however you can connect it where you choose along the tube.
Battery: CR2450, DC3, 540mA
Power Consumption: 2.5 mA
Operation Temperature: 0-120º F
LED reads ‘parts per million’
Pushfits for 8mm tube, eg. RHINO-TUBE (5/16”).
RED: over 150ppm
TURN ON : Squeeze Check-iT where you see the black dot. It will stay on for 5 seconds, or as long as the TDS READING is changing (think DRIVE-THRU CAR WASH METHOD).
If screen fades or cannot be switched on, pull battery case and replace the battery.
