Rowe Scientific do pH test strips, single use, in packs of 100. You can buy strips that have a range of pH 4.0 - 7.0 with an accuracy of 0.2-0.3. That might not sound accurate but most basic pH meters will only be accurate to 0.1 (just because it reads to 0.01 doesn't mean the unit accuracy is that good, read the manual) and cost $100s plus require constant calibration and attention to the pH electrodes.
