CODG-3000 Online COD Analyzer use principle of the potassium dichromate method for measuring COD: the water sample, potassium dichromate, silver sulfate solution (the catalyst oxidizes the linear aromatic hydrocarbon compound more fully) and concentrated sulfuric acid are heated to 175 ° C in the digestion tank. During this period, the chromium ion is reduced as the oxidant from the VI valence to the III valence and the color is changed. The degree of color change corresponds to the content of the organic compound in the sample, and the instrument directly displays the COD of the sample by colorimetric conversion. The main interference of CODG-3000 potassium dichromate type Online COD Analyzer for wastewater cod detection is chloride, which can be removed by adding mercury sulfate to form a complex.

The Hanna Phosphate High-Range Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphate High Range Checker uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.

The HI-98193 portable dissolved oxygen meter has extended ranges of up to 50 ppm and 600% saturation. When measuring dissolved oxygen, compensations for salinity, temperature and pressure are essential to improve the accuracy and precision of readings.Salinity compensation allows for direct determination of dissolved oxygen in saline waters. Temperature compensation is automatic with the probes built-in sensor, which features a one or two-point calibration. Pressure compensation with the meter's built-in barometer can be validated against a reference barometer, and if needed, can be recalibrated in user-selectable units (mmHg, inHg, atm, psi, kPa, mbar). With the internal barometer, the HI-98193 is able to compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information.Other features include measurement, methods and calculations for BOD, OUR and SOUR.Quick connect probeThe HI-764073 polarographic dissolved oxygen probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.Data LoggingThe HI-98193's log-on demand features allows users to store up to 400 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.GLP and On-Screen Help Comprehensive GL data is directly accessible by pressing the GLP key; the contextual help menu can be accessed to obtain on-screen information and assistance at the touch of a button.Key FeaturesQuick connect probe - The HI-764073 polarographic dissolved oxygen probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.Data Logging - The HI-98193s log-on demand features allows users to store up to 400 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.GLP and On-Screen Help - Comprehensive GL data is directly accessible by pressing the GLP key; the contextual help menu can be accessed to obtain on-screen information and assistance at the touch of a button.IP67 rated waterproof, rugged enclosureSalinity compensation - users can set the salinity valueAutomatic pressure compensation - built-in barometer with user-selectable units (mmHg, inHg, atm, psi, kPa, mbar)Built-in calculations - determination of Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR)Automatic polarisation of probe at startupReady to use PTFE preformed membrane capsApproximately 200 hours of continuous useOn-screen FeaturesBOD is calculated in mg per litre from the difference between the initial and final dissolved oxygen concentration readingsAll necessary parameters for BOD testing can be set and displayed at onceA list of all saved BOD data can be easily retrieved and shown on the LCD displayOUR results measured in mg of oxygen consumed per L per hourSOUR results measured in mg of oxygen consumed per g of volatile suspended solids per hourSupplied withHI-764073 polargraphic DO probeHI-7041S Electrolyte Solution for Polarographic Sensors, 30mlHI-7040 Bicomponent zero oxygen solutionPreformed PTFE membrane caps (2)DO protective capO-rings (2)Rugged carrying case100mL plastic beaker (2)HI-92000 PC softwareHI-920015 micro USB cableBatteriesInstruction manualQuality certificate4 metre cablePC Interface - Download test results to a computer programmed with HANNA's Windows compatible software (HI-92000), directly from equipment via a USB port or a RS232 cable outlet.

TDS meter adalah alat yang digunakan untuk mengukur Total Dissolved Solids (TDS), atau jumlah zat padat yang terlarut dalam air. Zat padat ini bisa berupa mineral, garam, atau logam yang mempengaruhi kualitas air. Berikut adalah langkah-langkah untuk menggunakan TDS meter:1. Nyalakan TDS MeterTekan tombol ON untuk mengaktifkan alat. Pastikan layar digitalnya menyala dan siap untuk digunakan.2. Celupkan Ujung TDS Meter ke dalam AirMasukkan ujung sensor TDS meter (biasanya bagian bawah alat) ke dalam air yang ingin Anda uji.Pastikan sensor sepenuhnya terendam air, namun jangan terlalu dalam hingga air mengenai bagian elektronik alat.3. Tunggu Pembacaan StabilTahan TDS meter dalam air selama beberapa detik hingga pembacaan pada layar digital stabil.Angka yang muncul adalah jumlah zat padat terlarut dalam air, diukur dalam satuan ppm (parts per million).4. Catat atau Simpan HasilnyaSetelah pembacaan stabil, Anda dapat mencatat nilai TDS.Beberapa TDS meter memiliki fitur hold, yang memungkinkan Anda menekan tombol untuk menyimpan pembacaan di layar.5. Matikan Alat dan BersihkanSetelah selesai, matikan alat dengan menekan tombol OFF.Bersihkan sensor dengan tisu atau kain lembut untuk menjaga kebersihan alat dan akurasinya.Interpretasi Hasil TDS:0-50 ppm: Air murni (biasanya hasil distilasi atau reverse osmosis).50-150 ppm: Air bersih dan layak konsumsi.150-300 ppm: Air dengan kandungan mineral cukup tinggi.300-500 ppm: Air mungkin masih aman, tapi sudah cukup tinggi kandungan zat padatnya.Di atas 500 ppm: Air tidak disarankan untuk diminum tanpa filtrasi lebih lanjut.Pastikan TDS meter dikalibrasi secara berkala agar tetap akurat.
