I love measuring and quantifying the world. I'm curious if I'm missing any good, essential tools. I'm also curious of some good, affordable fill-ins for some measurement capabilities that I may be missing. I currently have: Laser Distance Measure Radar gun Scales IR Temp Sensor pH Meter Thermometer Sound level meter Multimeter Cheap Torque Wrench I'm planning to grab (soon or otherwise): Handheld Anemometer Light/Illumination Sensor Caliper (Digital or otherwise. Is it dumb to settle for a 6"?) Hygrometer I'd like a way to measure: Pulling force (Planning to grab a hooked suit case scale but there may be a better way?) Everything else! I'm just curious if there's anything else that anyone can recommend or any tips anyone can give. I am on a budget, obviously, and will likely be shopping on Amazon with some money received for Christmas. My goal is to be able to measure most things that you can run into on a daily basis to quantify it and do so without buying a new tool every time that I find something new that I want to measure. I'm happy to improvise with things (such as my suit case scale idea for pulling force) but I'm curious if I'm missing any of the "primary colors" of measurement. Thanks!
