lamotte 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.

chemets 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.

D.O. Logger

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.

d.o meter

HI 9147 is designed for aquaculture applications. This unit is unique among our family of DO meters as it is supplied with a galvanic probe.

Unlike polarographic probes, galvanic DO probes require no conditioning time. When you need to measure multiple samples in a given period of time, pick it up and measure on demand.

HI 9147 is a must have for DO sensitive organisms or high bio-load environments.

The Professional Series ProODO® is YSI®'s first handheld optical dissolved oxygen instrument designed for sampling applications. The ProODO utilizes digital sensor technology which stores calibration data within the sensor. The ODO (Optical Dissolved Oxygen) luminescent sensor has no flow dependence, making it the perfect choice for applications where stirring is difficult or undesirable. Designed to fit in standard 300 mL BOD bottles. Calibration time and sensor maintenance are also reduced by a user-replaceable sensing element (requires annual replacement). There are no electrodes to clean or solutions to change. Based on usage, calibrations can be stable for up to one year and are stored in each sensor. This allows probes to be interchanged between instruments without recalibration. Unit is resistant to probe fouling from hydrogen sulfide and other gases.
• Stores 2,000 data sets, and USB connection allows interaction with Data Manager software.
• Supports English, Spanish, German, Italian, Norwegian, Portuguese and French.
• IP67-rated case. Salinity input rate 0-70 ppt.
• Runs on two C batteries.
• 8.5" L x 3.25" W x 2.25" H, weighs 1 lb.
