Electric Aeration kit
Electric aeration kit with pump. kit contains: - Diffusion stone - Filter 0.2 μ - Hose (1 m) - Pump - 2 W, 50 l / h Mounting and sterilization: - Boil water and lower the diffusion stone. - Cut part of the hose and Then heat the ends for simpler mounting. - Mount the filter, diffusion stone and pump.
Diffusion stone 2 microns
Diffusion stone with nipple and 2 microns pore size. Material: Stainless steel Nipple: 6.5 mm (1/4 ") Pore size 2 microns (for co2 or for oxygenation with oxygen stub) Manage the stone carefully and preferably with gloves so that the pores do not clog up.
Diffusion stone 0,5 microns
Diffusion stone with nipple and 0.5 microns pore size. Material: Stainless steel Nipple: 6.5 mm (1/4 ") Pore size 0.5 microns (for co2 or for oxygenation with oxygen stub) Manage the stone carefully and preferably with gloves so that the pores do not clog up.
Milwaukee MW600 PRO Dissolved Oxygen Meter with ATC
The Milwaukee MW600 PRO Portable Dissolved Oxygen meter is one of Milwaukee's most popular meters with its reliable and fast operation as well as its accuracy. The Milwaukee PRO DO Meter is preferred by people looking for lab level accuracy without the cost. The Milwaukee DO Meter is popular with everyone from field biologists and educators to fish farmers and koi pond owners.- Fast, easy-to-read results with large digital LCD readout- Repeatable, accuracy to ±1.5% FS- Lightweight and portable- Simple 2 point open air calibration (see video below)- Uses MA840 reinforced polarographic probe with an oxygen-permeable polytetrafluroethylene (PTFE) membrane sensor- 5 o-rings, membranes and one protective cap included- 10 feet probe cable for extra flexibility when testing- 70 hours of battery life with continuous use (battery included) with low battery warningSPECIFICATIONSO2 Range: 0.0 to 19.9 mg/LO2 resolution: 0.1 mg/LO2 Accuracy: ±1.5% Full ScaleCalibration: Manual on 2 points (zero and slope)Temperature Compensation: Automatic, from 0 to 30°CProbe: MA840 refillable polarographic probe includedMembranes: 5 includedEnvironment: 0 to 50°C / 32 to 122°F; max RH 95%Battery Type: 1 x 9V alkaline (included)Battery Life: Approx. 70 hours of continuous useDimensions: 5.7 x 3.1 x 1.6 inchesWeight: 7.5 ounces with batteryCARE AND USE“OPEN AIR” CALIBRATION PROCEDURE1. Remove the membraneTake the membrane off the end of the probe and dry the diode off.2. Zero out the displayConnect the probe to the base unit and turn the unit on. Your display should read 0.0. If it does not, go to the position “0” screw on the front of the unit with the screw driver provided and through the access hole make the unit display read 0.0.3. Fill the membraneGo to the membrane and put the “O” ring inside the membrane on the shoulder at the base of the threads. Fill the membrane to just short of the “O” ring with MA9071 electrolyte solution. Be sure that there are no bubbles inside the membrane. (Air bubbles are the main cause of calibration failure)4. Attach the membraneScrew the membrane on to the probe.5. Let stablizeTurn the meter on and hang the probe off the end of a table pointing down and let the unit display stabilize (this may take 5 to 15 minutes)6. AdjustPush down and hold the “Cal” button on the front face of the meter and with the screwdriver go to the front Cal position “100%” and make the display read 100.You are now calibrated.EXTRA TIPS- Watch for the membrane having wrinkles or stretch marks. If you see wrinkles, replace with a new membrane.- Always use fresh electrolyte solution (MA9071).
