Welch Allyn Turbidity Meter Bulb

I. Basic Information

Model: 997418-18

Brand: Welch Allyn

Compatible Devices: Hach 2100P, 2100Q, and 1900C Portable Turbidity Meters

Purpose: Serves as the light source for turbidity meters, providing a stable monochromatic light beam to ensure accurate turbidity measurements of water samples.

II. Key Features

Genuine factory-original halogen lamp with stable light output and slow light decay, ensuring consistency in instrument measurement data.

The filament manufacturing process is stable, and the light spectrum matches the optical detection standards of turbidity meters, eliminating the need for recalibration of the optical path upon installation.

The integrated design with lead wires allows for direct in-situ replacement; installation is simple, and the dimensions fit perfectly with the original lamp holder.

The glass envelope is flawlessly crafted with no impurity spots, preventing stray light interference and meeting the requirements for water quality laboratory testing.

III. Precautions for Use

Wait until the instrument has been completely powered down and cooled before replacing the lamp to prevent burns from high temperatures and lamp shattering.

Do not touch the glass emitting surface with bare hands; oils can cause the lamp to turn black and age rapidly.

After replacement, perform a zero-point calibration to ensure accurate turbidity readings.

Store in a cool, dry place to prevent filament breakage caused by vibration.
