DETECTO’s PHR portable height rod is simple to set up and easy to use. There’s no wall fastening necessary and it may be positioned against a wall or completely free standing due to its large floor plate. Two spacers provide additional stability when placed against a wall. The stadiometer measures from 4.5 in – 81 in and 11.5 cm – 205 cm with 0.125 in / 0.1 cm graduations visible on both sides of the height rod. The PHR stadiometer features a unique reversible head piece that lets you add a DETECTO DR400C digital floor scale at the base to measure weight and height simultaneously. If you use the PHR without a DR400C scale at the base, simply flip the head piece upside down. An optional PHR-CASE carrying case with shoulder strap is available that fits the PHR and DR400C.
