Introduction
A benchtop colorimeter is a laboratory instrument used to measure the color of liquid samples, such as water, beverages, chemicals, and pharmaceuticals, by comparing the color of the sample with standard color scales or by measuring the light transmitted through the sample, and it is used for quality control and analysis in the water, food, beverage, chemical, and pharmaceutical industries. The colorimeter measures the color of the sample by passing light of a specific wavelength through the sample and measuring the absorbance or the transmittance, and it calculates the color value, using standard color scales, such as the Hazen (APHA) scale for the color of water, the Gardner scale for the color of oils and resins, the iodine color scale, or other scales; the benchtop colorimeter is a compact instrument, with the sample placed in a sample cell or cuvette, and the measurement is made and the color value is displayed, with features such as calibration, the selection of color scales, and data management, and it provides a rapid and objective color measurement, and it is suitable for routine quality control; the colorimeter is available in various configurations, from simple single-parameter instruments to instruments with multiple color scales. Benchtop colorimeters are used for measuring the color of water and wastewater, for measuring the color of beverages and food products, for measuring the color of chemicals and pharmaceuticals, for quality control, for process monitoring, for compliance with specifications, and for many other applications. With their objective color measurement, benchtop colorimeters are essential for color analysis in the laboratory.

FAQ
Q1: What scenarios is this colorimeter used for?
A: It measures color or concentration from absorbance for water, chemical and colorimetric laboratory tests on the bench. It is used in laboratory, production and field settings, and our team can recommend a suitable configuration for your specific application.
Q2: What standards does it comply with?
A: It follows relevant colorimetric ASTM/ISO and GB/T standards, with calibration using standards. The relevant parameters are verified during final inspection before shipment, and compliance documentation or test reports can be provided on request for your quality records.
Q3: What is the warranty?
A: The colorimeter carries a 12 to 24 month warranty covering the unit. Cells are consumables. Damage from misuse is excluded.
Q4: Is it hard to operate?
A: Operation is simple after training: blank, measure and read. We provide a manual and guidance.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: Performance should be verified periodically using calibrated reference standards, with results logged in the equipment record. Most users perform this check every 6 to 12 months or according to their internal quality schedule. We provide the procedure, reference materials and formal calibration service if required.
Q7: Are consumables universal?
A: Compatible items are single-use consumables designed for this application. They are widely available in standard sizes, and we can supply them directly or confirm the specification so you can source them locally. Ongoing cost is limited to these consumables, and there are no proprietary locked parts.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include wavelengths, stored methods and data logging. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: No installation is required for this unit. It is ready to run after a simple power connection and the leveling steps shown in the manual. We supply a detailed operation guide and online setup videos, and on-site commissioning can be arranged separately if your facility requires it.
Q10: What samples are compatible?
A: It handles clear colored liquids within range. It is not for turbid samples without filtration, non-aqueous matrices, or targets outside methods.
