Vaisala Indigo80 handheld display meter

Vaisala Indigo80 handheld display meterheadWith a large battery capacity, high-resolution display screen, and memory that can accommodate up to 5.5 million data points, it is easy to visualize measurement values for a long time and check the readings of installed probes to determine if they need calibration. It can also be used for data recording, spot checks, and troubleshooting, and provides visualization of installed equipment data through a display screen. The use of an online refractometer can display optical images and other information of the instrument, in order to obtain accurate diagnostic views on site.

The following explains the advantages of using Indigo80 in conjunction with Polaris online refractometer.

1： Partial configuration and calibration - probes can be configured without shutting down

The Polaris online refractometer was pre configured upon delivery and the concentration coefficient was set according to the expected application. With Indigo80, you can quickly and easily adjust parameters without having to remove the probe from the process to reconfigure it through a laptop. Indigo80 can also be used to change signal damping parameters without affecting the process. Having a dedicated handheld device means there is no need to bring laptops or other devices into the processing area, otherwise it may cause safety issues or hinder cleanroom setup. For verification purposes, Indiqo80 provides you with a simple method to confirm the readings of the automated system during the calibration process.

2： Data Recording - Identifying Issues in the Process

Many on-site devices do not store historical data, but instead take snapshot readings for process control or generate alerts when process parameters exceed set limits. If an unexpected situation occurs and the operator is unsure of the cause, diagnostic tools need to be used. At this point, the combination of Vaisala Polaris and Indigo80 can provide assistance - because Indigo80 is battery powered, it can be connected to field devices overnight or for longer periods of time. Indigo80 can compare data with system data to determine changes over time, which can help make diagnoses.

3： Maintenance - Determine when sensors need to be cleaned

Although Polaris online refractometers require minimal maintenance due to their sturdy structure and lack of consumables and moving parts, maintenance may be necessary if the optical prism is covered with residue that causes image quality coefficient drift. The image quality coefficient is a numerical parameter that indicates the cleanliness of the prism. If drift occurs, the equipment Indiqo80 needs to be dismantled and cleaned. Recording the image quality coefficient over a period of time can help determine maintenance requirements. If the image quality coefficient decreases or shows significant changes, it may indicate the need for cleaning. Indigo80 can also be used as a display screen for Vaisala Polaris and other smart probes that do not come with a built-in display screen, and can choose between two views: graphical representation of current measurement values or probe history readings

Indigo80 and Vaisala Polaris online refractometers are valuable tools for collecting process insights and improving process and final product quality in various applications. When used in conjunction, the advantages are amplified. Vaisala Polaris can collect accurate concentration data, while Indiqo80 provides a convenient way to record, access, and visualize this data without the risk of process downtime.
