Series 200 & 300 Durablock® Solid Plastic Stationary Gage

SERIES MARK II MOLDED PLASTIC MANOMETERS

3% Accuracy for Stationary and Portable Applications

Series Mark II Molded Manometers are of the inclined and inclined-vertical types. The curved inclined-vertical tube of the Model 25 gage provides higher ranges with more easily read increments at low readings. The Model 25 is excellent for general purpose work. The Model 40 inclined gage provides linear calibration and excellent resolution throughout its range. The Model 40 is ideally suited for air velocity and air filter gage applications. Both gage types are capable of pressure measurements above and below atmospheric as well as differential pressure measurements. Included with each Mark II manometer are two tubing connectors for 1/8" pipe or sheet metal ducts, two mounting screws, 1 ounce bottle of indicating fluid, red and green pointer flags and complete instructions.
The Model 25 also includes 8' of flexible double column plastic tubing. Portable operation of the Model 25 is made possible by the use of the optional A-612 portable stand. A short piece of tubing can be slipped over the Model 25 pressure connections to contain the gage fluid in transit.
The Model 40 contains two 4-1/2' lengths of clear plastic tubing, a plastic swing-out stand and leveling screw for portable operation. It also features convenient rapid shutoff pressure connections and integral overpressure safety traps.

Questions

Question
We have a Dwyer gauge Mark II 25 on a waste oil furnace. Can you tell us how much heat it will withstand if we should get it too close to the heat source or how hot the gauge could get before readings would be incorrect.
Answer
The maximum temperature the Mark II 25 can be exposed to is 140 degrees F since it has many plastic components that cannot withstand direct heat.
Question
Could you confirm the instructions on setting the zero setting on Dwyer Model Mark II 25. I have two different instructions and want to know which one is correct.
Answer
Here is a link to the instruction manual for your model: https://dwyer-inst.com/PDF_files/D_58.pdf
The correct steps for zeroing are: Turn the zero set knob counterclockwise until it stops, then turn clockwise 3 full turns. This puts zero in approximately the middle of the travel adjustment in either direction. Remove the fill plug and fill with gage fluid until fluid reaches zero on scale. Minor adjustments can be made to adjust zero by adjusting zero knob. Replace fill plug. If gage is overfilled, remove excess by inserting pipe cleaner through the fill port to blot up excess fluid.
Question
Do you have a French manual for the Dwyer Mark II manometer inclided vertical version?
Answer
Unfortunately, we do not offer a French manual for Mark II at this time.
