QUANTOFIX test strips are semi-quantitative in nature. They meet all requirements for a modern rapid test. Most of the QUANTOFIX test strips can be carried out in 10-120 seconds. That makes the application very quick for the end user. All QUANTOFIX tests are ready to use kits. They are precalibrated and contain all necessary equipment and reagents. As "labs in a pocket" they are very handy for the end user. The color charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests. Make sure to store the packs in a dry, cool place at 39-86 °F (4-30 °C). Some tests are separately marked to require cool storage at 39-46 °F (4-8 °C). To ensure the longevity of the test strips, please close the tube immediately after removing a strip. The desiccant in the stopper effectively protects the strips against moisture. The strips can safely be used up to the date printed on the pack. The initial shelf life of the QUANTOFIX products is 2.5 years after production.

Very High Level Peroxide Test Strips, Food Grade, up 10% Conc. (Vial of 50)(50) StripsThe Very High Level (VHL) Peroxide test strips are designed for semi-quantitative testing of "food grade" hydrogen peroxide solutions. They utilize highly durable PVC strips that turn one color: black. Therefore, the concentration is determined by how long it takes for the strip to change to black.These VHL Peroxide test trips are suitable for hydroperoxides and ether peroxides. Polymeric peroxides are not detected.Di-tert-butyl peroxide, dicumyl peroxide, or tert-butyl perbenzoate do not react (or will react with significantly reduced sensitivity).

Manufacturer: Gain Express Holdings Ltd. Brand: Gain Express Model: A018351

This Dual meter is designed to measure the Conductivity and temperature (°C/°F) display simultaneously on its clear LCD. It has an IP65 Rating, waterproof and dustproof housing and waterproof membrane keypad. Default to Auto-ranging when power on. It determines and selects a range that gives the greatest resolution and accuracy. You can also opt to manual ranging and choose the range you prefer. For example you prefer a reading display of 0.50mS insteaqd of 500uS just press a button to select the mS range. Accuracy is a percent of full-scale, using the meter in its lowest range will result in the greatest accuracy. Perfect for both consumer or commercial use such as in water systems, aquaculture, drinking water production, monitoring the cleanliness of swimming pool & spa, nutrient, hydroponics, household, office, aquariums, teaching material for physics and chemistry lessons, galvanic shop, ionized water and laboratory. >The values are well readable with the large clear display.

Manufacturer: Mudder Brand: Mudder Model: MD-PH -0.01 Color: RED

The cap of meter keeps the sensor moist when stored upright, and can be applied as a container for sensor-conditioning. How to Calibrate NO Tools is Needed, but buffer calibration solution is needed. STEP 1: Turn on pH meter, Clean the electrode in distill water STEP 2: Immerse the electrode in pH 6.86 standard buffer solution STEP 3: Reset with screwdriver, until the display digital is 6.86pH. Then complete pH 6.86 calibration STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution STEP 5: Reset with screwdriver, until the display digital is 4.00pH. Then complete pH 4.00 calibration STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH Tips • The glass bulb of the electrode is fragile. Treat it carefully. Don't touch it by hard tools and fingers, suck the water on it gently when cleaning • Clean the electrode with distilled water every time before and after use • Open the battery case or replace battery, then need to recalibrate the meter Specifications Measure Range: 0.00-14.00 pH Resolution: 0. 01 pH Accuracy:±0.01 Ph Temperature Range: 0-50℃/ 122℉ Auto Temperate Compensation:0~50℃/ 122℉ Button Battery: 4 x1.5V AG-13 (included) Net Weight: 60g/1.83 oz Dimensions: 151 x 33 x 20mm /5.9 x 1.3 x 0.7 inch Package include 1 x Mudder pH Meter 1 x Adjustment screwdriver 1 x Soft Clean Cloth 1 x Mudder User's manual 1 X Package
