DISSOLVED OXYGEN TESTING

LAMOTTE DISSOLVED OXYGEN TEST KIT:

The dissolved oxygen test is one of the most important in aquaculture. Dissolved oxygen levels can affect fish respiration, as well as ammonia and nitrite toxicity. Salinity and temperature are both factors that affect dissolved oxygen levels. The LaMotte D.O. test kit can be used to test either fresh or salt water. This kit has an all liquid system and features a direct reading titrator. The direct reading titrator is a 1.0 ml microburet calibrated for direct readout in concentration; no counting of drops or calculations. 0-10 ppm O2 in 0.2 ppm increments. If the 10 ppm line is reached on the titrator without a color change, refill the titrator and continue. Be sure to add the initial 10 ppm to your final value. This will allow you to read samples with levels higher than 10 ppm. 50 tests per Kit.

HACH DISSOLVED OXYGEN TEST KIT:

The Hach D.O. test kit uses the modified Winkler method with drop count titration. 60 ml sample. Range tested is 0-20 ppm by 1 ppm. 100 tests per kit. Pre-measured reagent packages.

Kit accessories are clearance priced while current stock lasts

CHEMets DISSOLVED OXYGEN TEST KIT:

CHEMets test kits utilize self-filling ampules for colorimetric analysis of water quality. Vacuum pulls the sample up from a snap cup into the ampule when the tip is broken off. After tilting the ampule several times to mix the sample and reagent and waiting for the color to develop. Test kit contains 30 ampules, comparator, snap cup and instructions. Refill packs of 30 ampules are also available.

HOBO® DISSOLVED OXYGEN LOGGER - U26-001:

Measure oxygen concentrations in lakes, streams, rivers, estuaries, and coastal waters with the HOBO U26 Dissolved Oxygen Logger. This affordable and precise logger is recommended for aquatic biology and hydrology research projects. The HOBO U26 uses RDO® Basic (Rugged Dissolved Oxygen) optical DO sensor technology and is easy to maintain.

• Affordable, high performance dissolved oxygen (DO) monitoring with 0.2 mg/L accuracy
• Optical DO sensor technology for long-lasting calibration with less maintenance
• Dissolved Oxygen Assistant software corrects for measurement drift from fouling; provides salinity-adjusted DO concentrations and percent saturation
• Optical USB interface for high-speed, reliable data offload
• Easy-to-replace DO sensor cap lasts six months

NOTE: For DO measurements in saltwater, an adjustment for salinity is required. For waters with small changes in salinity (<2 ppt), a salinity meter reading typically provides enough accuracy.

OXYGUARD HANDY POLARIS DISSOLVED OXYGEN METER:

The OxyGuard Handy Polaris is a portable Dissolved Oxygen (DO) meter. It measures %saturation, mg/L (ppm), temperature and has salinity compensation. Measurements are compensated for temperature and barometric pressure. The probe is fully field serviceable. The Polaris has a larger display with backlight and offers automatic calibration, and a choice of language and units of measurement.

FEATURES AND BENEFITS:

OXYGUARD HANDY POLARIS 2 DISSOLVED OXYGEN METER WITH DATA LOGGING:

The Handy Polaris 2 hand-held meter makes it easy to measure dissolved oxygen and temperature. The flat foil pushbuttons are easy to operate and the instrument is always ready to use - just press the "on" button and measure. Dissolved oxygen values are shown both in mg/l (ppm) and % saturation - the user chooses which parameter is shown in large figures. Polaris 2 has a memory that can contain 3000 complete sets of data - each with values of mg/l (ppm), % saturation, temperature, time and date. Values can be stored either automatically at preset time intervals, or manually. You can group values according to the place of measurement. Stored values can be transferred to a PC using the Polaris Link, which connects to the PC via a USB cable. The datalogging and transfer capabilities, and other functions such as automatic calibration  and self-check of the probe and meter, combine with the well-known accuracy, reliability and low maintenance needs of the OxyGuard Handy series to make an instrument that will serve you well for many years to come.
