The simple test methods, intuitive control system and comprehensive manual are ideally suited for operators of all abilities. Precision optics combine long-life LEDs with interference filters and a highly accurate photo sensor for highly reliable results. N.I.S.T.-traceable calibration capability and verification standards assure continued validity and reliability. Over 120 test methods are available, including all of the most important water quality parameters, and methods can be easily updated by users. Data can be stored directly on the unit (up to 1000 data sets), or wirelessly transmitted to PC or printer. The robust IP68-rated waterproof enclosure is built for tough environments, allowing operation in all weather conditions. The waterproof hard-shell carry-case is resiliant yet lightweight, offering a complete portable solution for environmental monitoring.
HydroTest Pro Portable Spectrophotometer HT3000
The HydroTest Pro HT3000 is a modern, portable single-beam spectrophotometer that has been specifically designed for water testing. The powerful yet cost-effective instrument is housed in a waterproof carry case, with battery power supply (mains optional), offering a truly portable spectrophotometer, optimised for field applications. Spectral data is displayed on the screen graphically, as well as a list of maximum and minimum absorption levels. The single beam spectral photometer has no need for a warm-up period, speeding up obtaining results on site. The automatic self-test and wavelength adjustment system ensures accuracy throughout the lifetime of the halogen lamp. The spectrophotometer can also be tested using a NIST-traceable secondary standard filter set.
Turbidity, or cloudiness, has often been considered a superb first line indicator of water quality. Turbidity may be caused by growth of phytoplankton. Human activities that disturb land, such as construction, mining and agriculture, can lead to high sediment levels entering water bodies.. Erosion rates contribute large amounts of turbidity to nearby waters, and industries such as quarrying, mining and coal recovery can generate very high levels of turbidity from colloidal rock particles. High turbidity levels can reduce the amount of light reaching lower depths, which can inhibit growth of submerged aquatic plants, reducing oxygen levels. In drinking water, the higher the turbidity level, the higher the risk that people may develop gastrointestinal diseases. Suspended solids interfere with water disinfection with chlorine because the particles act as shields for the virus and bacteria. Similarly, suspended solids can protect bacteria from UV sterilisation of water. The HTTURB IR turbidity meter offers fast, precise on-site testing using the industry standard nephelometric method (scattered light at an angle of 90°). The wide range makes this a multi-purpose instrument for a variety of possible applications and the IR light source ensures suitability for both coloured and colourless liquids. The unit comes complete with calibration standards and accessories, packaged in a hard shell carry case.
HydroTest COD System
The HydroTest COD System HTCOD is designed for the determination of chemical oxygen demand index (COD) using the small-scale sealed-tube method. The industry standard dichromate method can be considered as an estimate of theoretical oxygen demand. With a wide measuring range from 0 – 15,000 mg/L O2, the HTCOD is ideal for waste water testing, offering a small handheld photometer with two LED light sources housed inside a waterproof sample chamber. The highly-sensitive equipment is compatible with mercury-free tube tests, with optional chloride compensation to remove interference, and utilises the popular photometric determination method. Standard solutions can be used to verify operation and accuracy of the instrument. The thermoreactor is compatible with other products in the HydroTest range, and can also be utilised for tube test digestion of TOC, total Chromium total Nitrogen and total Phosphate. The thermoreactor operates at three pre-set temperatures, with three pre-set reaction times, and offers automatic switch-off functionality with audible alarm.
