Hach DR300 Pocket Colorimeter Molybdenum Waterproof IP67 Photometer

Description

Product Overview

The Hach DR300 Pocket Colorimeter is engineered for professionals who need reliable, portable water quality analysis in the field or laboratory. Housed in a rugged, IP67‑rated enclosure, the instrument withstands dust, splashes, and temporary submersion, ensuring consistent performance even in demanding environments. The device operates on four AAA batteries, delivering power for up to 5,000 individual tests before a recharge is required, which translates to weeks of continuous use on a single set of batteries. Its Molybdenum cell provides a stable, chemically inert reaction chamber that minimizes interference and extends the lifespan of reagents. The built‑in data connectivity options include USB and Bluetooth, allowing seamless transfer of test results to computers, tablets, or cloud‑based laboratory information management systems (LIMS). The DR300 measures a single parameter at a time, making it ideal for targeted analyses such as nitrate, phosphate, or chlorine residuals, while its intuitive interface reduces training time and minimizes user error.

Usage

Designed for versatility, the DR300 excels in a variety of real‑world scenarios. Field technicians can deploy the colorimeter during routine river monitoring, drinking‑water source inspections, or wastewater discharge assessments, taking advantage of its lightweight form factor (6.2 x 2.7 x 1.3 inches) and 2‑pound weight for easy transport in backpacks or utility belts. In laboratory settings, the instrument serves as a rapid verification tool for sample batches, complementing larger spectrophotometers by providing quick, on‑the‑spot results that accelerate decision‑making. The waterproof rating also permits use in wet‑lab environments, such as around open tanks or during storm‑water sampling, without risk of damage. Because the device includes two glass and two plastic sample cells, users can switch between reusable and disposable options depending on the contamination level of the sample matrix. The battery‑powered design eliminates the need for external power sources, enabling continuous operation in remote locations where electricity is unavailable.

FAQ

What types of parameters can the DR300 measure?

The DR300 is a single‑parameter photometer, meaning it can measure one analyte per test. Common applications include nitrate, phosphate, chlorine residual, and iron, using Hach‑approved reagent kits that are compatible with the Molybdenum cell.

How long does a single battery last under typical use?

Under standard operating conditions—performing a test every few minutes—the four AAA batteries will support approximately 5,000 measurements, which generally translates to several weeks of continuous field work before replacement is needed.

Is the device compatible with existing Hach reagent kits?

Yes, the DR300 works with the full range of Hach reagent kits designed for single‑parameter colorimetric analysis. Users simply insert the appropriate reagent vial and follow the kit‑specific instructions for sample preparation.

Can the DR300 be used in temperatures below freezing?

The instrument is rated for operation from 0 °C to 40 °C. For temperatures below 0 °C, it is recommended to keep the device in an insulated container and allow it to warm to the operating range before use to maintain measurement accuracy.

What data formats are supported for export?

Data can be exported in CSV, XML, or proprietary Hach file formats via USB or Bluetooth. The exported files include timestamp, sample ID, absorbance value, and calculated concentration, facilitating easy integration with most data‑management systems.
