The Bluelab Carry Case provides a custom fit so you can use and read your Bluelab Meter right from the carry case. A firm outer casing offers impact reduction for your Meter. There are two pockets in the top of the case especially made for meter probes. The internal strap is a tidy way to tuck away the probe cables. Removable and adjustable straps provide even more comfort and convenience. The strap can be hung on the wall or used over your shoulder, keeping the Meter safe and dry in the carry case so only the probes go into the nutrient container. Ideal for use with the following Bluelab Meters: Bluelab Combo Meter, Bluelab pH Meter, Bluelab Soil pH Meter, Bluelab pH and ppm Pens. Meter not included with case.
