Comparison between models of Kalstein dissolved oxygen meters: YR01832, YR01833, YR01834 and YR01840

Kalstein, a recognized brand in the world of scientific instrumentation, offers high quality solutions for dissolved oxygen monitoring. This time, we will focus on models YR01832, YR01833, YR01834 and YR01840, analyzing their technical specifications and unique features.

Kalstein dissolved oxygen meters are high quality equipment that serve a variety of functions. Depending on your needs, you can opt for more automatic models such as the YR01840 or equipment with greater data storage capacity such as the YR01832. It is essential to take into account the environment in which the equipment is used and the differences in manual and automatic settings to make the right decision.

Dissolved Oxygen Meters – Descriptions and Technical Specifications

  1. YR01840 In-Line Dissolved Oxygen Monitor

This small and powerful meter is automatic in temperature compensation (0 to 40°C / 32 to 104°F) and allows pressure corrections between 60.0 to 112.5 kPa. Its salinity correction is from 0.0 to 35.0 g/L and operates under ambient conditions where the temperature does not exceed 60°C and relative humidity is less than 80%. This meter requires a DC24V power supply and weighs only 350g.

  1. Benchtop dissolved oxygen meter YR01832

This precision controller performs temperature adaptations up to 50°C and allows for manual salinity correction, allowing adjustment from 0.0 to 50.0 g/L. In addition, it offers the option of varied interval readings and includes a calibration overdue alarm. It also has a memory that allows storage of up to 1,000 sets of data.

  1. Benchtop dissolved oxygen meter YR01833

This high-precision equipment offers a measurement range of 0.0 to 20.0 mg/L with an accuracy of ± 0.2 mg/L. It has a temperature compensation from 0 to 50°C, manual pressure correction and salinity correction from 0.0 to 50.0 g/L.

  1. Tabletop dissolved oxygen meter YR01834

This model has a measuring range of 0.0 to 200.0%, with a resolution of 0.1% and an accuracy of ±2.0%. It has a temperature compensation from 0 to 40°C, pressure and salinity correction manually. Includes DO100 Polarographic probe sensor and 6-pin Nimi-DIN connector.

Comparison: Similarities and Differences

All four models share temperature compensation and have 1- or 2-point calibration capability. All have a pressure correction function. However, the differences lie in the measurement range, with the YR01833 and YR01834 offering a range up to 200.0% versus 20.0mg/L for the YR01832 and YR01840.

While the YR01833 and YR01834 offer manual corrections for both pressure and salinity, the YR01840 is fully automatic. On the other hand, the YR01832 excels with its storage capacity of up to 1,000 data sets.

Differences are also found in the operating environment, since the YR01840 allows environments up to 60°C, while the other models work with lower temperatures. In addition, as regards data protection, only the YR01832 offers a 4-digit password system.
