Introduction:
ET99724:The Lovibond® BOD-OxiDirect sensor system for permits exact and convenient measurement of the Biochemical Oxygen Demand (BOD) based on the respirometric principle. All results are shown in a big display directly in mg/l BOD without the need for time-consuming conversion using factors. In addition, the measuring period can be user-selected between 1 and 28 days.
The unit measures BOD levels via the pressure drop in the closed system during a defined period of time. Following measurement, the results are stored and can be called up to the display at any time. The inductive stirrer system not only mixes the sample but also ensures optimum gas exchange be-tween sample and gas space in the sample flask.
Alongside the BOD unit to determine BOD levels, a BOD system contains sample flasks, a non-wearing inductive stirrer system, overflow measuring flask to measure the sample volume, nitrification inhibitor and potassium hydroxide as an absorbent.
Features:
1) User friendly
2) Large brilliant graphic display
3) Graphical representation of measured values
4) USB & SD Card interface
5) Mercury-free, environmentally-friendly
6) Remote control
7) User-selectable time span from 1 to 28 days
8) Free individual programming of each of the six samples
9) Inductive stirring system, 110 – 240 V / 50 – 60 Hz
ET125SC:The thermoreactor will hold 25 round glass tubes with a 16 mm external diameter. It isdesigned for sample preparation in determining COD, total phosphorous, total chromiumand other parameters in water and sludge.This instrument, when combined with photometers and reagents and accessories forcolorimetric analysis, is part of a complete analytical setup capable of high precision andreproducibility, with a limited space requirement.
The instrument is highly resistant to chemical and mechanical corrosion through the use ofepoxy paint on metal surfaces. The block holding the test tubes is manufactured from analuminum alloy to ensure thermal homogeneity at all of the preset temperatures. The temperatureof the heating block is controlled by a microprocessor with PID logic. The temperatureprobe, Pt100 probe, performs a self calibration every time the instrument is turned on, toensure precision and reproducibility.Four different temperatures have been preset: 70, 100, 120, and 150°C, along with fourdifferent times: 30, 60, and 120 minutes or infinite time.The heating block is protected against overheating by a thermostat that turns off the powersupply when the temperature exceeds 180°C.
HI 88713:The HI 88713 is a high accuracy bench top turbidity meter designed to meet and exceed the requirements of ISO 7027 standard and is ideal for water quality testing.Using an infra-red light source it guarantees measurement repeatability and consistency. Variations in the intensity of the LED are also compensated for - limiting the need for frequent calibration.
Features:
1) Store up to 200 measurements in internal memory via LOG key
2) Access on-screen support via HELP key
3) Clear tutorial messaging
4) Step by step guide through the analysis process
5) Range of calibration options
6) Perform 2,3,4 or 5 point calibration using Hanna standards
7) Calibration points can be modified when user prepared standards are used
8) Complete Good Laboratory Practice (GLP) functions allow traceability of the calibration conditions
9) Wide bench top format with easy clean casing and user-friendly interface
10) Four turbidity measurement modes
11) Graphic backlit LCD display
PFXi 195/2:The instruments in the Lovibond PFXi-195 Series are efficient colorimeters for optically clear samples that meet the demand for consistent and reliable color data.
