Test Tube pH Pen, General Purpose Tip

Test Tube pH Pen, General Purpose Tip

Take accurate pH readings directly in your test tubes with our innovative Test Tube pH Pen. Specially designed to fit standard test tubes (16 x 50 mm or larger), this pen eliminates the need to transfer samples to a beaker, saving you time and reducing the risk of contamination.

This pH pen delivers highly stable and accurate readings, clearly displayed on a large LCD screen for easy viewing. Engineered for simple, one-handed operation, it allows you to multitask efficiently in a busy lab environment.

Key Features:

• Effortless Calibration: Automatically calibrates to pH 4, 7, and 10 buffers. For advanced applications, it can be manually adjusted to recognize non-standard buffer values.
• User-Friendly Functions: Includes a "hold" function to freeze a measurement on the screen for easy recording, and an auto-power-off feature to conserve battery life. A low battery indicator ensures you're never caught with a dead device.
• Versatile Probe Options: Choose the right probe for your specific application:
  • General Purpose Glass Probe: Ideal for general lab use and EPA-compliant water testing. Perfect for aqueous solutions in chemistry labs or wineries.
  • Penetration Probe: Features a durable, pointed tip designed for direct pH measurement in semi-solids like food (cheeses, fruits) and soil.
  • Flat Tip Probe: Optimized for surface pH measurements on materials such as meat, leather, paper, agar plates, and even skin.
